The main cause of cardiac tamponade is arrhythmia, which can occur in electrolyte disturbances as well as in inflammatory states. In patients with sudden onset of arrhythmias such as premature beats, and persistent tachyarrhythmias such as paroxysmal supraventricular tachycardia, atrial fibrillation, etc., the patient may experience a feeling of cardiac tamponade, a feeling of abnormal beating of the heart and a feeling of cardiac arrest. For inflammatory states, patients with fever and chills can experience twitching due to the whole body. For cardiac twitching, it is recommended to perform electrocardiogram and other examinations to clarify the presence of arrhythmia and the type of arrhythmia, and if necessary, to perform esophageal pacing and related examinations of cardiac electrophysiology, and appropriate treatment can be given.
