If you usually feel panic and palpitations, you should first rule out the possibility of arrhythmia. Patients who have this feeling of panic and palpitations frequently should go to the hospital for an electrocardiogram, including the electrocardiogram when they are quiet, at rest, or without episodes of panic, to determine how the patient’s basic heart rhythm and heart rate are and whether there are any ST-T changes. Secondly, when the patient has panic, he should go to the nearby hospital or community clinic for ECG examination as soon as possible, and take a picture of it with the cell phone to save it for the ECG or cardiologist to see, so as to determine what kind of arrhythmia it is, and the feeling of panic and palpitation is nothing but a slow heartbeat or a fast heartbeat. For slow heartbeat, the main consideration is atrioventricular block and sinus bradycardia, and often the electrocardiogram can reveal whether the patient needs medication or even surgery to install a pacemaker. If the patient has a fast heartbeat, it can also lead to panic palpitations. Such panic palpitations have to be determined if they are related to a slow heartbeat, and some people still need a pacemaker based on a slow heartbeat that later reflexively causes tachycardia. If some patients have a fast heartbeat, such as tachycardia, atrial flutter, or paroxysmal supraventricular tachycardia, they usually need to be treated with electrophysiological examination and radiofrequency ablation based on regular medication, in order to achieve a certain cure rate. Anemia and hyperthyroidism also often cause panic attacks, and blood tests and thyroid function should also be performed.
