Basic Dysrhythmia Review for the Nurse Rhythm Strip Packet 2024 with Solutions ECG - Answer -Electrocardiogram Electrocardiogram - Answer -A recording of the electrical activity of the heart. Shows depolarizzation (systole) and repolarization (diastole) The action potential of cardiac muscles begins with the opening of __________ channels, allowing for an influx of these ions into the cardiac cells. This rapid influx generates the rapid __________________ (_________ movement) of the ECG waveform, known as the ______ __________. This impulse spreads across the heart, leading to the _____________ of cardiac muscle fibers. - Answer -Sodium Depolarization (upper movement) QRS complex Contraction After the rapid depolarization (_____ __________), ___________ channels close, and ___________ channels open. This allows the efflux of these ions from the cells, resulting in ________________ (________) and is represented by the ____ ________ on the ECG. - Answer -QRS Complex Sodium Potassium Repolarization (diastole) T Wave __________ ions play a crucial. Role in the plateau phase of the cardiac action potential, which occurs after ________________ and before _______________. During this phase ____________ channelsopen, allowing an influx of these ions into the cells, which sustains ________________ prolonging ______________. This plateau phase is see on an ECG waveform as the _____ ________. - Answer - Calcium Depolarization Repolarization Calci
