OPINION OF THE COURT

The facts in this case are as follows: Appellee, Barbara Molineux, is the Administratrix of the estate of her brother, Michael T. Dalton. Mr. Dalton died at Taylor Hospital on October 20, 1979, some ten hours after admission for injuries sustained in an automobile accident. Appellee instituted suit against Appellants in the Court of Common Pleas of Delaware County on November 6, 1981, two years and seventeen days after Mr. Dalton’s death. Appellee sought to recover damages, pursuant to the Pennsylvania Wrongful Death and Survival Statutes, for the alleged negligent treatment and wrongful death of the decedent. Defendants in the suit, Appellants herein, included four doctors, Emergency Medical Associates, and Taylor Hospital. Defendant-Appellants all responded to the Complaints filed against them by raising as New Matter, pursuant to Pa.R.C.P. 1030, the defense of the current two-year statute of limitations.1 Appellee’s Reply asserted that the reason the action was not filed within two years from the date of death was that Taylor Hospital “refused” to make the records of decedent’s treatment available even after “repeated” requests (R. 44a). Defendant-Appellants moved for summary judgment on the grounds that the action was barred by the statute of limitations, but the trial judge, the Honorable *401Dominic D. Jerome, initially declined to dismiss the Complaints since there were factual issues in dispute.

Counsel for each party stipulated that the trial judge alone would determine the applicability of the statute of limitations as to all of the defendants (R. 149a). A hearing was held before Judge Jerome on March 19, 1984, at which the testimony of two sworn witnesses (both testifying for Appellee) was taken in open court on the disputed factual issues (R. 148a-216a). At the conclusion of this hearing, Judge Jerome dismissed the action and entered judgment in favor of all defendants on the grounds that the action was time-barred (R. 233a-225a). Judge Jerome subsequently filed a Memorandum Opinion confirming his decision of March 19, 1984, 346 Pa.Super. 639, 499 A.2d 404, to dismiss the Complaints. Appellee argues (and Superior Court agreed) that the hearing Judge Jerome conducted was on the motions for summary judgment, and that Judge Jerome, in fact, granted summary judgment to Defendant-Appellants. Defendant-Appellants contend that the hearing was, in essence, a bench trial; that Judge Jerome made determinations of a factfinder weighing the evidence; and that he entered judgment pursuant thereto.

After a careful review of the record, we conclude that the latter interpretation of what happened is entirely accurate. Pa.R.C.P. 1035 dealing with the “motion for summary judgment” makes no provision for a factual hearing. At most, it provides for the use of affidavits in resolving the motion. What Judge Jerome did here, with the obvious consent of all parties, was to bifurcate the case, and hold a full hearing or bench trial on the statute of limitations question, a subsidiary issue. He then decided the statute of limitations question on the disputed facts. See, Schaffer v. Batyko, 227 Pa.Superior Ct. 62, 323 A.2d 62 (1974). Judge Jerome’s Opinion clearly indicates that this was his view of what was done, and it is the only conclusion consistent with Rule 1035 which provides, in subsection (6), for the rendering of summary judgment only where “... there is no genuine issue as to any material fact____” A hearing to take the *402testimony of witnesses, where any party is free to call witnesses, takes the matter beyond the realm of summary judgment because the factfinder has now been given the opportunity to weigh evidence and determine credibility, if necessary.

The trial court summarily rejected applicability of the so called discovery rule as a possible means of extending the two year statute of limitations, relying on this Court’s decision in Anthony v. Koppers Company, Inc., 496 Pa. 119, 436 A.2d 181 (1981). In that case, we held that the so called discovery rule, which provides that a statute of limitations commences to run from the time an injury or cause of action becomes known, or from the time that one using all due diligence should have discovered the injury or cause of action, did not function so as to extend the period for filing wrongful death or survival actions.

At the trial or hearing, Appellee attempted to show that Defendant-Appellants were estopped from asserting the defense of the statute of limitations because they allegedly lulled Appellee and her attorney into a false sense of security causing them to rely (to their detriment) on promises to send hospital records, which promises it took over nine months to fulfill. This alleged fraud or concealment was only chargeable, of course, to Defendant-Appellant Taylor Hospital. The other Defendant-Appellants could not, therefore, be properly held to be estopped to raise the statute of limitations defense because of Taylor Hospital’s conduct, and the trial court summarily concluded the same.

As to Taylor Hospital, the trial court concluded after the evidentiary hearing that no fraud or concealment had occurred.

The governing principles relevant to the establishment of a claim of estoppel based on fraud or concealment are as follows. Where, “through fraud or concealment, the defendant causes the plaintiff to relax his vigilance or deviate from his right of inquiry,” the defendant is estopped from invoking the bar of the statute of limitations. Schaffer v. Larzelere, 410 Pa. 402, 405, 189 A.2d 267, 269 (1963). *403Moreover, defendant’s conduct need not rise to fraud or concealment in the strictest sense, that is, with an intent to deceive; unintentional fraud or concealment is sufficient. Walters v. Ditzler, 424 Pa. 445, 227 A.2d 833 (1967); Nesbitt v. Erie Coach Company, 416 Pa. 89, 204 A.2d 473 (1964). Mere mistake, misunderstanding or lack of knowledge is insufficient however, Schaffer v. Larzelere, supra; and the burden of proving such fraud or concealment, by evidence which is clear, precise and convincing, is upon the asserting party. Nesbitt v. Erie Coach Company, supra.

The evidence as found by Judge Jerome indicates that counsel for Appellee first requested her decedent’s records from Taylor Hospital by letter dated March 21, 1980. Enclosed in the letter was an authorization for the release of records. In June, 1980, Appellee’s counsel’s associate attorney called Taylor Hospital to ascertain why the records had not been sent. A representative of the Hospital said the records would be forthcoming shortly. A month later, another inquiry was made to the Hospital regarding the whereabouts of the records. On December 4, 1980, a letter was sent to the billing department at Taylor Hospital again requesting the records. A week after this letter was sent, a spokeswoman from the medical records office at Taylor Hospital called and informed counsel’s associate that the records would not be sent out until they received a “short certificate.”2 Counsel’s associate attorney sent out another letter of request on December 18, 1980, with the appropriate short certificate. The records were forwarded on or about December 28, 1980, to counsel’s office.

The trial court found that the evidence failed to disclose any fraud or concealment on the part of the Hospital. Requests were made to the Hospital on a few occasions and apparently went unanswered, concluded the trial court, *404because counsel failed to send the short certificate. When this document was finally sent, the Hospital responded immediately and sent the records. The trial court therefore dismissed the action as to Taylor Hospital, as well as to the other defendants. Judge Jerome’s Opinion also notes that although there had been a delay of approximately ten months by the Hospital in providing the records, there was still ample time for Appellee’s counsel to determine whether or not there was a cause of action against Taylor Hospital. Counsel did not institute a timely action even though counsel received and reviewed the hospital records,ten months before the statute of limitations ran. This unexplained lack of diligence does not tilt the equities in favor of Appellee.

Nevertheless, Superior Court (Montemuro, Roberts and Bloom,3 JJ.) reversed in a Memorandum Opinion. While conceding that it was possible to conclude that Taylor Hospital’s delay in sending the records was due to mere mistake or misunderstanding, Superior Court thought that it was equally possible to infer that the delay here was occasioned by fraud or concealment. Since conflicting inferences could be drawn from these facts, Superior Court determined that the supposed grant of summary judgment in favor of Taylor Hospital had been improper. Superior Court also found that summary judgment had been improperly granted because the trial court’s conclusion that Anthony v. Koppers Company, Inc., supra, precluded application of the discovery rule to wrongful death and survival actions was erroneous. Superior Court reasoned that Anthony v. Koppers Company, Inc. had been based on the language of the previous statutes of limitation for wrongful death and survival actions, but that the discovery rule would apply to wrongful death and survival actions under 42 Pa.C.S. § 5524(2). In support of this conclusion, Superior Court relied on its own opinion in Pastierik v. Duquesne Light Co., 341 Pa.Superior Ct. 329, 491 A.2d 841 (1985), *405which we have since reversed, however, at 514 Pa. 517, 526 A.2d 323 (1987).

We granted allocatur because we were dismayed by the state of the record in which there was apparent confusion on the part of all concerned about whether summary judgment had been granted, and because we were likewise concerned by the refusal of the Superior Court to follow this Court’s recent decision in Anthony v. Koppers Company, Inc., supra. For the reasons set forth below, we reverse.

It is discernable from this record that a summary judgment was not granted here, and that one could not have been granted under Pa.R.C.P. 1035 once the trial judge, by agreement of the parties, took sworn testimony in open court at an adversarial type hearing. Summary judgment is an “eyes-only” procedure. The trial court’s judgment here was entered after a full non-jury trial on the statute of limitations issues. It is entitled to the same deference on review than any other judgment deserves, which has been entered after a full trial on the merits before a judge.

It is also clear from this record that there is no substantial evidence that Taylor Hospital engaged in fraud or concealment, intentional or otherwise, which would now estop it from pleading the bar of the statute of limitations. That is the conclusion to which the trial court came, and there is nothing in this record which would justify an appellate court in reversing that determination.

Finally, this Court recently decided in Pastierik v. Duquesne Light Company, supra, that the discovery rule does not function so as to extend the periods for filing actions under the current statutes of limitations for wrongful death and survival actions in Pennsylvania. That decision is controlling here.

Appellee’s attorneys have little to complain about. After they received the requested information from Taylor Hospital, they waited over ten months to take any action. Such a *406lack of diligence cannot be excused.4

Reversed.

I dissent, and in so doing, I reiterate the conclusion I reached in Pastierik v. Duquesne Light Co., 514 Pa. 323, 526 A.2d 323 (1987) (Larsen, J., dissenting), that the discovery rule is applicable to a wrongful death action brought *407pursuant to 42 Pa.C.S.A. § 5524(2). See also, McGowan v. University of Scranton, 759 F.2d 287 (3d Cir. 1985). Because appellee, Barbara Molineux, could not have discovered that her brother was permitted to bleed to death in the hospital emergency room and that his death may have been the result of medical malpractice, until she received his hospital records, I would hold that the cause of action in this case did not accrue until December 23, 1980, and that the statutory period of limitations did not begin to run until that date.

Accordingly, I would affirm the Order of Superior Court and would permit appellee the right to amend her complaint to allege facts supporting her claim of delayed accrual, including the circumstances excusing delayed discovery.
