Precursors of Sudden Death

The main precursors of sudden death include the following points: 1. Chest tightness and palpitations: Frequent or suddenly worsening chest tightness and palpitations may indicate inadequate cardiac blood supply or arrhythmia, signaling a potential risk of sudden death. 2. Physical fatigue: Unexplained extreme fatigue, insomnia, and anxiety may indicate underlying heart problems. This is especially concerning when accompanied by edema and chest tightness, which may suggest serious conditions like myocarditis. 3. Fainting: Fainting is an important precursor to sudden death and may be caused by a sudden decrease or cessation of heart activity leading to insufficient cerebral blood supply. 4. Bradycardia: Particularly in elderly individuals, excessively slow heart rate can lead to cardiac arrest and subsequent sudden death. 5. Limb numbness: Numbness in one or both limbs, or visual disturbances such as sudden vision darkening, may be warning signs of stroke, which can also lead to sudden death.
