Which physiological response is often associated with panic attacks?

Heart palpitations are a common physiological response associated with panic attacks. During a panic attack, individuals often experience an intense feeling of fear or discomfort that can trigger the body's "fight or flight" response. This response involves the release of adrenaline, which can lead to an increased heart rate and the sensation of heart palpitations — a feeling that the heart is pounding, racing, or fluttering.

During a panic attack, the body activates several physiological changes, including increased heart rate, heightened blood pressure, and the potential for sensations such as chest tightness. Heart palpitations specifically reflect the body's acute reaction to stress and anxiety, making this symptom particularly relevant in the context of panic attacks. Understanding this connection can help individuals recognize the symptoms of a panic attack and manage their responses effectively.
