###Human: Is it normal to have rapid heartbeat in a Wolf Parkinson white syndrome patient? ###Assistant: Hi. Wolf Parkinson white syndrome is caused by the presence of extra pathway of the heart electricity which causes parts of the heart to be excited before others and sometimes the connection between the normal pathway and the extra pathway cause what is called reentry cycle which causes an attack of tachycardia (rapid heart beats). Treatment options include medical and ablation. Medical: Propafenone 150 mg tablet every eight hours (control heartbeats). In severe cases ablation using a catheter is required. Beta blockers like Metalor is not suitable as it blocks the normal pathway and enhances the extra abnormal pathway. I recommend that you follow up and send me your ECG and echocardiography report in order to identify the type and severity of the arrhythmia.
