Anxiety is known to cause cardiac discomfort, and its main causes consist of the following: First, patients with anxiety disorders are often accompanied by autonomic disorders, and the most common point of dysfunction is palpitations, and many patients will have experiences similar to premature beats, and even severe patients will have a sense of near-death appear. Secondly, patients with anxiety disorders are prone to sensory hypersensitivity, and many patients will feel that the sound of their heartbeat is very prominent, or even so severe that their heart sounds loud, thus worrying that their heart has this or that problem. There is also the fact that when anxiety is present, a person’s heart rate is increased, so the patient will feel panicky and uncomfortable. The heart discomfort caused by anxiety is often functional, which means that most patients with anxiety disorders do not have organic heart disease. Treatment only requires anti-anxiety medication, and some patients can be assisted with a combination of metoprolol medication to lower their heart rate, and most patients when their anxiety improves, their heart discomfort will also improve.
