The major advantage of ECG is its ability to assess all electrical activities within the heart whereas. A normal heart rate is between 60 and 100 When this happens the hearts lower pumping chambers ventricles dont have time to fill up.

. 192 Cardiac Muscle and Electrical Activity. The curvature of the spiral wave is the key to the formation of the core. During a bout of SVT the heart rate can soar as high as 250 beats or more per minute.
The center of the spiral wave is called the core and the distribution of the core in 3 dimensions is referred to as the filament. However in cases of extreme shock and hypo-perfusion pulse less electrical activity is observed. 202 Blood Flow Blood Pressure and Resistance.
In its simplest form. This condition occurs when faulty electrical signals in the heart override the hearts normal pacemaker triggering a series of fast heartbeats. 61 The term spiral wave is usually used to describe reentrant activity in 2 dimensions.
195 Development of the Heart. The 3-dimensional form of the spiral wave forms a scroll wave. 201 Structure and Function of Blood Vessels.
By observing this electrical activity the heart rate is calculated with the assumption that each of the observed electrical pulses results in a cardiac contraction cycle.
