I have suddenly developed an apparent heart arrhythmia in which my rate seems to drop down to half its normal rate. I went in to emergency about two seeks ago and the monitor confirmed this drop. But an ECG showed that alternate beats were premature and did not register on the monitor. during these 15 to 20 minute episodes I have an enormous loss of energy and have been quite concerned. halter monitor confirmed irregularity but did not detect the very slow rate. Last evening I had the condition constantly. In trying to analyze the problem, I realize that it began at the time I began taking Cholestyramine. This past weekend I had not taken any of it until late Sunday afternoon and the heart rate drop began again shortly thereafter.
