WebDisturbance in ventricular relaxation results in the disruption of pressure conditions in the left ventricle. Ventricular pressure should drop rapidly and substantially during diastole, but if relaxation is impaired, the drop in pressure will be slower and less pronounced. This ultimately leads to increased diastolic pressure in the left ventricle. WebIt is important to be relaxed and warm during an ECG recording because any movement, including shivering, can alter the results. Sometimes this test is done while you are …
