Echocardiography can be used to directly visualise right ventricular wall thickness. The preferred technique is the trans-oesophageal approach giving a view of 4 chambers. The normal thickness of a right ventricular free wall ranges from 2-5 millimetres, with a value above 5 mm considered to be hypertrophic. [10]
Afterload is the mean tension produced by a chamber of the heart in order to contract. It can also be considered as the ‘load’ that the heart must eject blood against. Afterload is, therefore, a consequence of aortic large vessel compliance, wave reflection, and small vessel resistance (LV afterload) or similar pulmonary artery parameters (RV afterload
This could possibly be a result of excessive right ventricular (RV) wall stress during very high volumes of training, which is known to be causing a disproportionate remodeling of RV. [ 35 ] [ 36 ] In a 2003 study, 46 endurance athletes, mostly cyclists, presented with various symptoms suggestive of arrhythmia of RV origin. 59% of participants ...

Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
When Pastor Frank Wulf thinks about his congregation being unable to worship in their home of 100 years, he is reminded of the Old Testament scripture of the Israelites in exile.
The normal transmitral flow profile has two peaks – an E and an A wave. [citation needed] The E peak arises due to early diastolic filling. Most filling (70-85%) of the ventricle occurs during this phase. The A peak arises due to atrial contraction, forcing approximately 15-20% of stroke volume into the ventricle.
