Investigation of palpitations

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Palpitations are a common patient complaint, often occurring during normal physiological states like exercise or stress.
• They can also result from substance use (e.g., caffeine, nicotine) or medications affecting heart rate.
• Abnormal palpitations may indicate underlying cardiac arrhythmias, though not always.

Purpose of the Study:

• To outline a diagnostic approach for patients presenting with a history of palpitations.
• To highlight the importance of thorough patient evaluation in identifying the cause of palpitations.

Main Methods:

• Emphasis on detailed patient history to differentiate normal from abnormal palpitations.
• Inclusion of physical examination findings relevant to cardiac assessment.
• Highlighting the utility of the 12-lead electrocardiogram (ECG) as a primary diagnostic tool.

Main Results:

• Normal palpitations are often linked to identifiable triggers like exercise, emotions, or substance intake.
• Abnormal palpitations warrant further investigation for potential cardiac arrhythmias.
• Many arrhythmias do not present with palpitations but with other symptoms like syncope or chest pain.

Conclusions:

• A systematic approach focusing on history, physical examination, and ECG is crucial for evaluating palpitations.
• These simple, accessible tools aid in distinguishing benign causes from potentially serious cardiac conditions.
• Prompt and accurate diagnosis is essential for appropriate patient management.
