ECG

4. An arrhythmia where individual muscle fibres contract independently and totally disorganized, such as in the atria or ventricles.
6. An increase in ventricular muscle mass that results in increased electrical activity and increased height of the QRS complex.
8. The special area of the right atrium where the electrical discharge for the normal heart rhythm originates.
9. on the concepts for ECG interpretation, here are 10 important words and clues for your crossword puzzle:
10. A type of second-degree heart block characterized by progressive PR interval lengthening until an atrial beat fails to conduct.
11. The characteristic early slurred upstroke of the QRS complex seen in pre-excitation syndromes like Wolff-Parkinson-White.

1. The process of the ventricular mass returning to its resting electrical state, represented by the T wave on an ECG.
2. A descriptive term for a slow heart rhythm, which may be associated with athletic training, hypothermia, or fainting.
3. The electrical change associated with muscle contraction, normally initiating in the sinoatrial node for each cardiac cycle.
5. Acute myocardial injury typically first indicated by ST segment elevation and the eventual appearance of pathological Q waves.
7. A condition often manifested on an ECG by horizontal depression of the ST segment, especially during exercise.
