Overview

There are a vast number of causes of palpitations, including namely any condition that causes the heart to be rapidly, forcefully, or irregularly. In general, palpitations may be caused by primary abnormalities in the heart (tachycardia or forceful heart beating), reductions in oxygen carrying capacity (anemia), reductions in the volume of blood circulating (dehydration), sympathetic nervous system stiumlation (fever, exertion, panic attacks, drugs), excess hormone production (hyperthyroidism).

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

• Acute coronary syndrome
• Malignant hypertension
• Myocardial infarction
• Third degree AV block
• Ventricular arrhythmia

Common Causes

• Amiodarone
• Anemia
• Atrial fibrillation
• Atropine
• Cardiac glycosides
• Diseases of the valvular structures
• Flurazepam
• Heart block
• Heart failure
• Hypercapnia
• Hypoglycemia
• Hypoxia
• Insulin
• Nitrates
• Panic disorders
• Pregnancy
• Pyrexia
• Supraventricular tachycardia
• Sympathomimetics
• Thyrotoxicosis
• Ventricular tachycardia
