Third Degree AV Block (Complete Heart Block).Second Degree AV Block Mobitz I (Wenckebach).These impulses stimulate and coordinate atrial and ventricular myocardial contractions that provide cardiac output. Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occur as a result of alterations within the conduction of electrical impulses. These signals are transmitted to produce a record of cardiac activity. An EKG uses electrodes attached to the skin to detect electric currents moving through the heart. One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart’s electrical activity as waveforms. Use this EKG interpretation cheat sheet that summarizes all heart arrhythmias in an easy-to-understand fashion.
