WitrynaAn impulse ( action potential) that originates from the SA node at a relative rate of 60-100 bpm is known as a normal sinus rhythm. If SA nodal impulses occur at a rate less than 60 bpm, the heart rhythm is known as sinus bradycardia. If SA nodal impulses occur at a rate exceeding 100bpm, the consequent rapid heart rate is sinus tachycardia.
WitrynaThe myogenic heart beat is initiated by a patch of modified heart muscle itself. It is found in hearts of molluscs and vertebrates including human beings. Origin of heart beat (Fig. 18.10): The mammalian heart is myogenic (myomuscle, genic originating from). It means the heart beat originates from a muscle, (however, it is regulated by the nerves). optipro pre-injection isopropyl wipesAn electrocardiogram is a recording of the electrical activity of the heart. Under normal conditions, electrical activity is spontaneously generated by the SA node, the cardiac pacemaker. This electrical impulse is propagated throughout the right atrium, and through Bachmann's bundle to the left atrium, stimulating the myocardium of the atria to contract. The conduction of the electrical impulses throughout the atria is seen on the ECG as the P wave. porto-power porta power accessoriesWitrynaBidirectional ventricular tachycardia (BiVT) is a rare ventricular tachycardia (VT) where dual QRS morphologies alternate on a beat-to-beat basis.
