| Type 1 (n = 39) | Type 2 (n = 79) | Type 3 (n = 10) | |
|---|---|---|---|
| Age (years) | 43 ± 16 | 53 ± 13 | 45 ± 15 |

| Echocardiography | |||
| LA diameter (mm) | 42 ± 7 | 46 ± 8 | 50 ± 7† |
| LVEF (%) | 70 ± 4‡ | 64±7 | 64 ± 5 |
| IVS D (mm) | 13 ± 3 | 17 ± 6 | 20 ± 5† |
| Posterior LV wall (mm) | 9 ± 3 | 10 ± 3 | 11 ± 2 |

| Heart rate (bpm) | 68 ± 10 | 67 ± 10 | 57 ± 7§ |
IVS D = interventricular septum diastole; LA = left atrial; LV = left ventricular; LVEF = left ventricular ejection fraction; MAP = mean arterial blood pressure; VF = ventricular fibrillation; VT = ventricular tachycardia. For the NYHA class analyses and the echocardiographic parameters only data from the HCM patients were available.
