A significant study reports that the risk for recurrence of heart failure in recovered PPCM patients as a result of subsequent pregnancy is approximately 21% or better. [30] The chance of relapse may be even smaller for those with normal contractile reserve as demonstrated by stress echocardiography.
A mammary souffle is a maternal cardiac murmur heard over the breasts. [citation needed] A mammary souffle is present in late pregnancy or during lactation. [4] It is a benign continuous heart sound, which disappear after lactation. It's supposed to arise from superficial arteries supplying the lactating breast and for that reason called a ...
Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
Sometimes, heart murmurs disappear on their own. This happens when the cause of the heart murmur is no longer present. Monitoring will help determine how the condition changes. [1] It may stay the same, worsen, or improve. In other cases, the condition causing the heart murmur may not prompt any further tests.
According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
The diagnosis of hypokalemia (not enough potassium) can be suspected when there is a history of diarrhoea or malnutrition. Loop diuretics may also contribute. The electrocardiogram may show flattening of T waves and prominent U waves. Hypokalemia is an important cause of acquired long QT syndrome, and may predispose the patient to torsades de ...
Hypokalemic periodic paralysis (hypoKPP), also known as familial hypokalemic periodic paralysis (FHPP), [1] is a rare, autosomal dominant channelopathy characterized by muscle weakness or paralysis when there is a fall in potassium levels in the blood (hypokalemia).
A pansystolic heart murmur may be heard on auscultation of the chest. The murmur is usually of low frequency and best heard on the lower left sternal border. It increases with inspiration, and decreases with expiration: this is known as Carvallo's sign. However, the murmur may be inaudible due to the relatively low pressures in the right side ...
