Tachycardia cardiac output
WebCardiac output (CO) is a measurement of the amount of blood pumped by each ventricle in one minute. To calculate this value, multiply stroke volume (SV), the amount of blood pumped by each ventricle, by heart rate (HR), in contractions per minute (or beats per minute, bpm). It can be represented mathematically by the following equation: WebThe ventricular rate is typically very high (100–250 beats per minute) and cardiac output is affected (i.e reduced) in virtually all cases. Ventricular tachycardia cause immense strain on the ventricular myocardium, …
