Objectives: This study aimed to examine whether P wave peak time (PWPT), a predictor of atrial fibrillation (AF), is significantly higher at the time of diagnosis in cryptogenic ischemic stroke patients.

Patients and methods: The retrospective was conducted with 118 individuals (72 males, 46 females; mean age: 66.4±13.8 years) with cryptogenic ischemic stroke in the patient group and 118 individuals (77 males, 41 females; mean age: 63.2±16.1 years) without cerebrovascular disease in the control group between January 2021 and December 2023. The groups were compared regarding PWPT.

Results: As a result of multivariate regression analysis, PWPT-D2 and PWPT-V1 were found to be independent predictors of cryptogenic ischemic stroke. In the ROC analysis, when PWPT-D2 was >51.5 msec, the sensitivity for the diagnosis of cryptogenic ischemic stroke was found to be 80%, and the specificity was 76%. When PWPT-V1 was >46 msec, the sensitivity for the diagnosis of cryptogenic ischemic stroke was found to be 75%, and the specificity was 73%.

Conclusion: P wave peak time is an important predictor of cryptogenic ischemic stroke. The reason for the high PWPT level in these patients may be undetected AF. Therefore, longer-term rhythm Holter may be recommended in these patients.
