Fetal heart rate monitoring. 30 weeks pregnancy. The human heart beats more than 2.8 billion times in an average lifetime. [60] The heartbeat of a human embryo begins at approximately 21 days after conception, or five weeks after the last normal menstrual period (LMP), which is the date normally used to date pregnancy in the medical community.
A saltatory pattern of fetal heart rate is defined in cardiotocography (CTG) guidelines by FIGO as fetal heart rate (FHR) baseline amplitude changes of more than 25 beats per minute (bpm) with a duration of >30 minutes. [25] [27]
The heart adapts to the increased cardiac demand that occurs during pregnancy in many ways. Cardiac output (Lit./Min.): 6.26; Stroke Volume (Ml.): 75; Heart Rate (Per min.): 85; Blood Pressure: Unaffected; Cardiac output increases throughout early pregnancy, and peaks in the third trimester, usually to 30-50% above baseline.

Some studies assert that PPCM may be slightly more prevalent among older women who have had higher numbers of liveborn children and among women of older and younger extremes of childbearing age. [13] [33] However, a quarter to a third of PPCM patients are young women who have given birth for the first time. [3] [4] [13] [29] [34] [35 ...
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]
Heart disease is the top cause of death in the United States, with statistics showing it was responsible for more than 700,000 deaths in 2022. While heart disease is more prevalent in men than in ...
In the US, the average age at which women bore their first child advanced from 21.4 years old in 1970 [11] to 26.9 in 2018. [4]The German Federal Institute for Population Research claimed in 2015 the percentage for women with an age of at least 35 giving birth to a child was 25.9%.
“Our analysis supports an association between milk intake higher than 300 ml per day and higher rates of ischaemic heart disease, and myocardial infarction [heart attack] specifically, in women ...
