“…The hemodynamics of pulsus alternans have been reported and evaluated by palpation [1], cardiac catheterization of the ventricles and great vessels [3][4][5][6][7][8][9]15], Doppler echocardiography [8,16], and phonocardiography [16]. To our knowledge, this is the first report of pulsus alternans measured from an epicardial coronary artery.…”

Pulsus alternans is typically found in patients with left ventricular systolic dysfunction. We describe a woman with biventricular systolic dysfunction and pulsus alternans in the right ventricle, pulmonary artery, and aorta. Coronary angiography revealed an intermediate stenosis in the proximal left anterior descending (LAD) coronary artery. Pulsus alternans was demonstrated in the mid LAD using a 0.014" guidewire-mounted pressure sensor. An abnormal fractional flow reserve was measured in the LAD. Cathet. Cardiovasc.

“…It has also been reported in acute transient ischemia [3] and in patients with normal hearts during or after supraventricular tachycardia [4]. Right ventricular alternans has also been described previously, usually in patients with severe right ventricular dysfunction [5][6][7][8][9].…”
