Hi Doc, my wife having WPW in the past and she gone through some procedure. Few months after, she is still continue having extra hearth pulputation and difficult in breathing. She went for a 24hrs ECG monitoring and found that she is having high hearth pulputation upto 120 per min in rest situation. And she went to untra-sound to check the condition of the hearth, but the Doc said that the heart is strong and normal, and the high pulputation is normal as well.... If everthing is normal, why the extra pulputation is there and she continue suffer short in breathing few times a day now? Please help. Thank you.
