P-wave peak time (PWPT), defined as the interval from P-wave onset to its maximal amplitude, has emerged as a novel electrocardiographic marker of atrial conduction and hemodynamic stress. Increasing evidence suggests that PWPT prolongation accompanies elevated ventricular filling pressures, atrial stretch, and chronic atrial remodeling across a spectrum of ischemic conditions, including both obstructive coronary artery disease and ischemia with no obstructive coronary arteries (INOCA). In addition to serving as a marker of acute ischemia, PWPT also appears to capture long-term atrial structural and electrophysiologic changes, including fibrosis and conduction slowing. These same processes are central to the development of atrial fibrillation, providing a biologically plausible link between PWPT prolongation and arrhythmogenic risk. Moreover, given its simplicity and compatibility with computerized ECG analysis, PWPT represents a promising adjunctive marker for cardiovascular risk stratification.
