Cardiac arrhythmias, especially ventricular ones, are a mechanism associated with sudden natural death.
General
Associations
- Myocardial infarction.[1]
- Hypertensive heart disease.[2]
- Commotio cordis.
- Arrhythmogenic right ventricular cardiomyopathy.
Non-cardiac
- Electrocution.
- Hyperthermia.
Microscopic
Features - associated with ventricular fibrillation:[3]
- Myofiber break-up - key feature.
- Fractures of the sarcomeres perpendicular to the long axis.
- Associated with square nuclei.
