Pt # | Duration of symptoms | Clinical scenario or symptoms | Monitors used (duration of use) | Apple Watch findings | EP study findings |
|---|---|---|---|---|---|
1 | 3 years | Palpitations | Holter monitor (48 h) | Tachycardia alert | AVRT |
2 | 2 years | Palpitations and chest pain | Patch monitor (7 days) | Tachycardia alert | AVNRT |
3 | 2 years | Palpitations with presyncope | Patch monitor (11 days) | Tachycardia alert | AVRT |
4 | 2 years | Exercise-induced palpitations and chest pain | Patch monitor (1 day × 2 trials, failed due to skin reaction to adhesive) | Triggered ECG showing SVT | AVNRT |
5 | 2 months | Palpitations and presyncope, intermittent WPW | Event monitor (30 days) | Triggered ECG showing SVT | WPW/AVRT |
6 | 7 years | Palpitations | Multiple event monitors of unknown wear time | Tachycardia alert | AVNRT |
7 | 1 year | Palpitations thought to be panic attacks, intermittent WPW | Multiple trials of patch monitors (3-, 4-, 6-, 8-, 10-, and 10-day monitoring periods) | Tachycardia alert | WPW/AVRT |
8 | 1 year | Palpitations | Patch monitor (14 days) | Tachycardia alert | AVNRT |
9 | 2 months | Palpitations with exertion | Patch monitor (1 day, terminated due to anxiety with device) | Triggered ECG showing SVT | No EPS—medical therapy |
10 | 6 years | Palpitations and chest tightness, thought to be due to asthma | Patch monitor (13 days) | Triggered ECG showing wide complex tachycardia | No EPS—medical therapy |
