Factors Responsible for ICD Shock Episodes
| Shock Type | Total, n | Shock Episodes, n | P Value | |
|---|---|---|---|---|
| Group 1 | Group 2 | |||
| Appropriate shock | 29 | 24 | 5 | 0.153 |
| IS | 11 | 11 | 0 | <0.001 |

| Abnormal sensing | 1 | 1 | 0 | 0.192 |
This table analyzes shock episodes from the standpoint of shock rather than by patient; a given patient could receive ≥1 IS (from any or all of the subcategories) and/or ≥1 appropriate shock. AF indicates atrial fibrillation; ICD, implantable cardioverter‐defibrillator; IS, inappropriate shock.
