HEALTHSTREAM TELEMETRY & ECG EXAM 2023/2024 Mechanical & Electrical Activity - CORRECT ANSWER-- Correlation between the electrical and mechanical functions of the heart - Electrical activity stimulates the heart to contract - Electrocardiogram (ECG) show both functions - Electrical pulse= action potntial Cardiac Monitoring - CORRECT ANSWER-- Used to diagnose dysrhythmias, chamber enlargement, MI/myocardial ischemia, monitor effects of electrolyte imbalances of medication administrat...

Excitability - Answer- the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization - Answer- occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity - Answer- the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex: the wave of depol...
