How to Manage Anxiety-Induced Tachycardia

In human physiology, tachycardia is a term used to describe an elevated heart rate, exceeding 100 beats per minute, which is considered above the normal resting rate. This phenomenon is not always related to cardiac issues as there are various types of tachycardia, each with different underlying causes.

Types of Tachycardia

Two primary types of tachycardia are paroxysmal tachycardia and sinus tachycardia. Paroxysmal tachycardia is associated with specific pathophysiological conditions such as heart lesions, pharmacological intoxications, or gastro-cardiac reflexes. On the other hand, sinus tachycardia is a more common occurrence due to various circumstances like temporary physical exertion, caffeine consumption, or the manifestation of an anxious emotional state. The latter scenario is referred to as anxiety-induced tachycardia.

Symptoms of Anxiety-Induced Tachycardia

Anxiety-induced tachycardia is a sudden event that occurs in the context of fear or stress. Unlike other cardiac symptoms, such as atrial fibrillation, the heartbeat in anxiety-induced tachycardia is accelerated but remains constant and does not exhibit any rhythm irregularities.

To identify anxiety-induced tachycardia, it's essential to evaluate its onset and remission patterns: during an anxiety attack, individuals often feel their heart pounding. Fortunately, this sensation typically lasts for a short duration as the heart rate gradually returns to normal, along with the subsiding of other symptoms.

Anxiety-induced tachycardia is also accompanied by strong emotions of fear, confusion, and a sense of helplessness. Identifying these sensations, emotions, and thoughts can help distinguish anxiety-related tachycardia from other heart issues.

Causes of Anxiety-Induced Tachycardia

When we perceive a situation as threatening, the brain activates the sympathetic nervous system, which prepares us to react to danger. This activation causes muscle tension, increased breathing rate, elevated blood pressure, and increased heart rate, potentially resulting in anxiety-induced tachycardia. However, the brain cannot sustain this activation for extended periods. In the absence of a real threat, the parasympathetic system intervenes to restore balance, leading to relaxation and a state of rest.

Managing Anxiety-Induced Tachycardia

To manage anxiety-induced tachycardia, it's crucial to recognize it and allow the parasympathetic system to restore calm. Some strategies to manage panic attacks include breathing control, relaxation techniques, and distraction. It's also important to address lifestyle habits to prevent anxiety-induced tachycardia from becoming a frequent occurrence.

Is It Dangerous?

While anxiety-induced tachycardia can be quite distressing, it is typically not dangerous. However, it can pose a risk to individuals with pre-existing heart conditions. Long-term studies have found correlations between anxiety and coronary heart disease, and frequent stress can significantly compromise and weaken the immune system, making individuals more vulnerable.

When It Becomes Chronic

If anxiety-induced tachycardia becomes a regular occurrence, it could indicate a Generalized Anxiety Disorder, a common but serious condition characterized by chronic worry and tension lasting more than six months. Symptoms include difficulty managing worries, irritability, a tendency to startle easily, headaches, fatigue, muscle tension, and tremors. If stress and anxiety become constant elements of daily life, it's important to seek professional help to address anxiety and prevent its long-term consequences.
