How to tell heart rate from an ECG?
... 1500 mm per minute. HR (by which we mean ventricular rate or QRS rate) is the number of cardiac cycles per minute (5) or more correctly the number of times the heart beats per minute. It can be estimated by counting the number of QRS complexes in a 10 second period and multiplying that by 6 or by co ...
