Problems:
Definition:—Certain conditions depending upon a fault in the nervous control of the heart or upon impairment of nerve influence within the heart. These conditions are manifested by alterations in the action of the heart and often by serious interference with its normal functional activity. They are not in themselves, with perhaps the exception of angina pectoris, of a serious character; among these are arythmia, palpitation, tachycardia, bradycardia and angina pectoris.
