Absent fourth heart sound as a marker of adverse events in hypertrophic cardiomyopathy with sinus rhythm. [PDF]
Ann Noninvasive Electrocardiol, 2022 Background Patients with hypertrophic cardiomyopathy (HCM) in sinus rhythm commonly show the fourth heart sound (S4). The lack of S4 may be a marker of impaired atrial function in HCM patients with sinus rhythm.
