Hemodynamic accompaniments of angina: a comparison during angina induced by exercise and by atrial pacing

The hemodynamic responses of nine patients with severe coronary artery disease were studied during the precipitation of angina by both supine exercise and increasing rates of atrial pacing. Tension-time index and the first derivative of left ventricular pressure pulse (LV dp/dt) at the onset of angi...

Zusammenfassung:The hemodynamic responses of nine patients with severe coronary artery disease were studied during the precipitation of angina by both supine exercise and increasing rates of atrial pacing. Tension-time index and the first derivative of left ventricular pressure pulse (LV dp/dt) at the onset of angina were significantly higher ( P
