Common Causes Of Heart Palpitations And Anxiety

Heart palpitations and anxiety can be triggered by a variety of factors, often related to both physical and emotional conditions. Understanding these causes can help individuals identify when to seek medical attention or make lifestyle adjustments.

Emotional And Psychological Triggers

Stress, fear, and anger are among the most common emotional causes of heart palpitations. When the body experiences intense emotions, it releases adrenaline, which can cause a rapid or irregular heartbeat. These episodes are usually temporary and subside once the emotional state stabilizes.

Physiological And Medical Causes

Fever And Elevated Body Temperature

High fever can significantly affect heart rate. As body temperature rises, the heart works harder to regulate internal functions. Typically, for every 1°C increase in body temperature, the heart rate may increase by approximately 10 to 15 beats per minute. This response is a natural part of the body's effort to cool itself down and maintain homeostasis.

Anemia And Blood Conditions

Anemia, a condition characterized by a deficiency in red blood cells or hemoglobin, can also lead to heart palpitations. The heart compensates for reduced oxygen levels in the blood by beating faster to deliver more oxygen to tissues. If palpitations are accompanied by fatigue, dizziness, or shortness of breath, it may be a sign of underlying anemia.

Physical Activity And Lifestyle Factors

Exercise and physical exertion naturally increase heart rate, which can sometimes be perceived as palpitations. This is typically a normal physiological response and not a cause for concern unless the sensation is unusually strong or persists after rest.

Cardiac And Serious Health Conditions

Certain heart conditions can cause sudden or unexplained heart palpitations. For example, paroxysmal supraventricular tachycardia (PSVT) can occur unexpectedly, while ventricular tachycardia may even happen during sleep. These types of palpitations are not always linked to obvious triggers and may require immediate medical evaluation.

If you experience unexplained heart palpitations, especially if they are frequent, intense, or accompanied by other symptoms like chest pain or fainting, it is important to consult a healthcare professional. An electrocardiogram (ECG) can help diagnose any underlying cardiac issues and guide appropriate treatment.
