depolarization | When the electrical system of the heart stimulates myocardial cells, ____ occurs, resutling in the contraction of the stimulated heart muscle. |
precordial | ____ leads measure the electrical activity among six specific points on the chest wall and a point within the heart. |
standardization | has been determined by international agreement so that an ECG can be interpreted in the same way anywhere in the world. |
artifact | A ___ is an unwanted, erratic movement of the stylus on the paper caused by outside interference. |
6 | To calculate the heart rate from the ECG recording, count the number of P waves in a ____ second strip (30 large squares) and multiply by 10. |
PAC | occurs when the atria contract before they should for the next cardiac cycle. |
shock | An implanted cardioverter-defibrillator, or ICD, monitors the heart rhythm and delivers a(n) ___ to the heart if it detects a dangerous ventricular tachycardia or fibrillation. |
stress testing | Cardiac ___ is performed to observe and record the patients cardiovascular response to measured exercise challenges. |
cardiac event monitor | The ______ is a small recording device that can be worn up to 30 days to catch events that are difficult to record in a 24-hour period on a Holter monitor. |
