Hi, my significant other has a defribrilating pace maker and recently was placed on a diuretic due to significant water retention. He lost 10+ in one week, but the medicine leaves him feeling week. Now, he is experiencing cold-sweaty clamminess, intermittently during nite and day. He is seeing his cardiologist on Tuesday morning, but this is troubling. He has not felt well since July 5. He has had his pacemaker for more than 5 years (It was recently replaced due to battery decline).
