A system for the detection of cardiac events occurring in a human patient is provided. At least two electrodes are included in the system for obtaining an electrical signal from a patient's heart. An electrical signal processor is electrically coupled to the electrodes for processing the electrical signal and applying tests to determine whether a cardiac event has occurred. When the processor detects some types of changes in heart rate, event detection is altered or suspended for a period of time.

What is claimed is: 1. A cardiac event detection system for detecting a cardiac event in a patient comprising:(a) at least two sensors for sensing an analog signal from said patient's heart;(b) a device coupled to said sensors, said device having an analog-to-digital circuit system contained therein

What is claimed is: 1. A cardiac event detection system for detecting a cardiac event in a patient comprising:(a) at least two sensors for sensing an analog signal from said patient's heart;(b) a device coupled to said sensors, said device having an analog-to-digital circuit system contained therein for digitizing said analog signal to produce a digitized waveform;(c) a processor contained in said device and electrically coupled to said analog-to-digital circuit system, said processor configured to:(i) compute from the digitized waveform heart rate information;(ii) based on the heart rate information, determine whether a change in heart rate has occurred;(iii) responsive to a determination that a change in heart rate has occurred, determine the relative time the change in heart rate occurred;(iv) responsive to the determination that a change in heart rate has occurred, based on the relative timing of the change in heart rate, selectively apply a first test to detect a cardiac event.
