Take a ECG measurement when the patient is experiencing a problem is the best way to capture the event. Time is critical in treating a patient with heart problem. Proper monitoring and fast treatment are important for improving the patient's condition. A patient should know the patterns of his "regular" ECG waveform. This would form a baseline for comparison with future readings and for detecting any changes in conditions. This would show how the patient is responding to different medications. False heart attack can cause lots of stress and may induce a real one. Take an ECG reading would ease your mind; however you would need to have some understanding of ECG or your "normal" ECG. This Device is intended to monitor the ECG Waveform, not for Medical Diagnosis. Never use the device in critical situations.
