WebCharacteristic peaked P wave of cor pulmonale Peaked P waves (> 0.25 mV) suggest right atrial enlargement, cor pulmonale, ( P pulmonale rhythm), [1] but have a low predictive value (~20%). [2] A P wave with increased amplitude can indicate hypokalemia. [3] It can also indicate right atrial enlargement. [4] WebQ Waves The pathophysiological basis of Q waves differs depending on the disease process (eg, ischemic or infiltrative myocardial disease versus classical asymmetrical hypertrophic cardiomyopathy (HCM). Notably, the diagnostic criteria also differ.
