Ventricular contraction – systole. AV valves close . Lub sound heart. Semilunar valves close. Dub sound heard. Ventricular relaxation (filling with blood again) – diastole. Heart rate – the number of beats per minute (around 72 bpm) Stroke volume. is the amount of blood passing through the heart with each beat (about 80mL) Cardiac output

Ventricular relaxation, AV valves open (tricuspid and mitral), Pressure higher in atria causing ventricles to fill with blood. Systole: 1/3 cardiac cycle. Atrial contraction pumps blood to ventricles. With volume of blood in ventricles, ventricular pressure greater than atrial, so mitral and tricuspid valves shut

Dilatation of the veins promotes peripheral pooling of blood and decreases venous return to the heart, thereby reducing left ventricular end-diastolic pressure and pulmonary capillary wedge pressure (preload). Arteriolar relaxation reduces systemic vascular resistance, systolic arterial pressure, and mean arterial pressure (afterload).

In 1998 Paulus et al. developed the European Criteria for HFpreEF [4]. This group suggested that there must be objective evidence of HF with a normal or mildly impaired systolic function (left ventricular ejection fraction (LVEF) > 45%) and abnormal left ventricular (LV) relaxation. All three criteria are required for the diagnosis of HFpreEF.

V1 lead is the best lead to view ventricular activity and differentiate between right and left bundle branch blocks. The only way to view V1 is with a five lead system. Therefore, MCL1 was designed to overcome the inconvenience of a five lead system and provide all the advantages of V1 viewing.

The E/e’ ratio has been shown to correlate with LV filling pressures and abnormal LV relaxation in patients with preserved LVEF (8,9). LV end-diastolic volume, left atrial diameter and LV mass were measured as reported previously (6).

o In most cases, HFPEF is probably caused by diastolic dysfunction (due to decreased left ventricular filling, with abnormal left ventricular relaxation or distensibility during diastole) [Sanderson, 2007; European Society of Cardiology, 2008; Sanderson and Yip, 2009]. o Most people with reduced LVEF also have diastolic dysfunction.
