| Type of LTA | Number of studies | Sample size | Pooled prevalence |
|---|---|---|---|
| Overall | 16 | 31,475 | 6.285% (CI: 4.698–8.084%; I2 = 94.67%) |
| Complete atrioventricular block | 4 | 11,397 | 2.129% (CI: 0.877–3.912%; p = 0.0116; I2 = 72.76%) |
| Asystole | 3 | 1369 | 2.036% (CI: 1.216–3.061%; p = 0.2739; I2 = 22.84%) |
| Ventricular fibrillation | 8 | 12,538 | 2.674% (CI: 1.159–4.789%; p < 0.0001; I2 = 89.58%) |
| Ventricular tachycardia | 7 | 30,359 | 3.343% (CI: 1.844–5.264%; p < 0.0001; I2 = 97.52%) |
LTA: life-threatening arrhythmia, CI: confidence interval, p: probability value.
