Disease Name	Causes	ECG Characteristics
Ventricular tachycardia^[1]^[2]^[3]^[4]	Ischemic heart disease Illicit drug use such as cocaine and methamphetamine Structural heart diseases Electrolyte disturbances Congestive heart failure Myocarditis Obstructive sleep apnea Pulmonary artery catheter Long QT syndrome	Ventricular tachycardia originates from a ventricular focus. Lasts more than 30 seconds. Broad QRS complexes: rate of >90 BPM.
Ventricular fibrillation^[5]^[6]^[7]^[8]	Acute coronary ischemia Cardiomyopathies Congenital heart disease Myocardial infarction Heart surgery Electrolyte abnormalities	Poorly identifiable QRS complexes and absent P waves The heart rate is >300 BPM Rhythm is irregular
Asystole^[9]^[10]	Hypovolemia Hypoxia Acidosis Hypothermia Hyperkalemia or Hypokalemia Hypoglycemia Cardiac Tamponade Tension pneumothorax Thrombosis Myocardial infarction Thrombosis Pulmonary embolism Cardiogenic shock Degeneration of the sinoatrial or atrioventricular nodes Ischemic stroke	There is no electrical activity in the asystole
Pulseless electrical activity^[11]^[12]	Hypovolemia Hypoxia Hydrogen ions (Acidosis) Hypothermia Hyperkalemia or Hypokalemia Hypoglycemia Tablets or Toxins (Drug overdose) such as beta blockers, tricyclic antidepressants, or calcium channel blockers Tamponade Tension pneumothorax Thrombosis (Myocardial infarction) Thrombosis (Pulmonary embolism) Trauma (Hypovolemia from blood loss)	Several ppattern are possible including: Normal sinus rhythm Sinus tachycardia, with discernible P waves and QRS complexes Bradycardia, with or without P waves
Pulmonary embolism
