Moreover, greater lung function impairment was related to poorer heart rate dynamics. fresh dog food calculatorWebbDescribe how a heartbeat is initiated and coordinated? The sinoatrial node (SAN) sends a wave of electrical activity across the atria causing atrial contraction. The non-conducting tissue stops the immediate contraction of the ventricles.
