PHYSIOLOGIC SENSORS TO AUGMENT PVC BURDEN INFORMATION

Abstract: systems and methods are disclosed to a medical device system comprising a cardiac signal sensing circuit, a heart sound sensor, a signal processing circuit, and a control circuit. the cardiac signal sensing circuit produces a sensed cardiac signal representative of cardiac depolarization signals when connected to electrodes. the heart sound sensor produces a sensed heart sound signal representative of vibrational sounds of the heart. the signal processing circuit identifies premature ventricular contractions (pvcs) using sensed cardiac signal information. the control circuit is configured to calculate a pvc burden of the patient using pvc information, determine that the calculated pvc burden exceeds a threshold pvc burden and that the patient is asymptomatic for heart failure, determine that sensed heart sound signal information indicates heart failure of the patient, and present a recommendation of an echocardiogram for the patient to a user.
