Across
- 3. A complete absence of electrical activity in the heart, indicating the heart is not beating at all.
- 4. A chaotic, disorganized electrical activity in the ventricles, resulting in the heart quivering instead of pumping blood
- 5. Heart rate below 60
- 6. arrhythmia characterized by irregular and rapid beating of the heart's upper chambers
Down
- 1. Heart rate above 120
- 2. Electrical activity is present on the ECG, but the heart muscle doesn't contract effectively to produce a pulse
- 4. A rapid heart rhythm originating in the ventricles, causing the heart to beat too fast to pump effectively.
