A person is known to suffer coronary arteriosclerosis and suddenly complained of chest pain; the hospital diagnosis was acute myocardial infarction ---- 6 hours later he died of cardiac arrhythmia.
What is the cause of death?
What is the manner of death?
 
             
                                                            
                            Manner of Death
 
The Manner of Death is a legal classification describing the circumstances under which the death occurred. The five main categories are Natural, Accident, Suicide, Homicide, and Undetermined.
Since the death resulted from a progression of internal, natural disease processes (arteriosclerosis $\rightarrow$ myocardial infarction $\rightarrow$ arrhythmia), the manner is:

Cause of Death
 
The Cause of Death is the disease or injury that starts the train of events leading to death. The death certificate lists the sequence of events.
Proximate Cause (the final event): Cardiac Arrhythmia
Intermediate Cause (what led to the final event): Acute Myocardial Infarction
Underlying Cause (the disease that began the lethal chain): Coronary Arteriosclerosis (or Coronary Artery Disease)
In official forensic terms, the Acute Myocardial Infarction would be listed as the immediate cause of death, with Coronary Arteriosclerosis as the underlying cause.
