1. Respiratory effects on systolic time intervals during pericardial effusion;Spodick, D.H.; Paladino, D.; Flessas, A.P.;Am J Cardiol,1983
2. Effects of normal breathing and expiratory apnea on duration of the phases of cardiac systole. Am tory haemodynamic responses are exaggerated not only in florid cardiac tamponade"l 12 but also, as we have shown, in effusions without clinical signs of tamponade. Our findings differ from some of the results of;Pigott, V.M.; Spodick, D.H.;HeartJ,1971
3. Relationships between left ventricular ejection time, stroke volume, and heart rate in normal individuals and patients with cardiovascular disease;Weissler, A.M.; Peeler, R.G.; WH, Jr, Roehil;Am HeartJ
