WebPhysiology of Cardiac Conduction. A healthy heart is capable of altering cardiac output to match the physical demands of the body. The normal adult resting heart rate is between 60-100 beats per minute (bpm) but when stressed or exercising the same heart may rapidly increase to a rate of 140 bpm or more. The change in rate (chronotropism ... WebIncreased epinephrine from the adrenal medulla binds to the β1 receptor in the heart to increase the heartbeat rate (chronotropic effect) and strength (ionotropic effect). In addition, the rapid relaxation of the ventricle during diastole is facilitated (lusitropic effect). These actions contribute to an overall increase in cardiac output.
