What is r peak?

R peak refers to the highest point on an electrocardiogram (ECG) waveform, which corresponds to the depolarization of the ventricles of the heart. It is the most prominent and easily identifiable feature on an ECG. The R peak is of particular significance in the diagnosis of various cardiac conditions and abnormalities, including arrhythmias, myocardial infarctions, and heart blockages. The amplitude, duration, and shape of the R peak can provide important information about the functioning of the heart and can help doctors to make accurate diagnoses and develop treatment plans for their patients.
