What Causes Low Heart Rate In Fetus
Many causes.: Bradyarrhythmias (heart block, hypothyroidism, drugs) can lower the fetal heart rate persistently, however the most common reason is cord or placental accidents that threaten the fetal well-being. Your obstetrician and/or perinatologist should be able to help you avoid this problem. ...Read more
Slow heart rate, also called bradycardia, is defined as a resting heart rate (pulse) less than 60 beats per minute. Having a heart rate less than 60 is not necessarily abnormal. In fact, people in good cardiovascular shape have a low heart rate. People with certain heart conditions may take medications which lower the heart rate as one of ...Read more
Parent had pacemaker put in due to low heart rate (30's-40's). Had high BP and is overweight. What are the likely causes of decreased heart rate?
Slow heart rate: Just answered this earlier. We had no definite cause to this. The sinus node, or the heart pacer is just simply slow in firing, could have been from previous ischemia but we can't say for certain. It is not a common condition but we see it enough and yes more in the elderly, so the ischemic theory probably is true. ...Read more
Head compression.: Typically, the fetal heart rate decreases episodically with contractions during the pushing stage of labor as the fetal head is compressed and rapidly descends in the birth canal. Head compression causes a parasympathetic neural discharge that slows the heart rate as long as the intracranial pressure continues. Other causes: cord compression, placental failure can also occur. ...Read moreSee 1 more doctor answer
Thyroid disorders.: The proper answer to your question is that typically the baseline fetal heart rate does not correlate with fetal growth. Rare scenarios where this general statement would not be accurate include severe maternal hypothyroidism or excessive intake of antithyroid medications in hyperthyroid women that subsequently affect the fetus and its growth curves. ...Read more
What happens to cardiac output and after load when when heart rate is low? does it increase because high heart rate causes decrease in CO
Dehydration: The most common cause of combined low blood pressure and high heart rate would be dehydration. Anemia could also cause a higher heart rate, but not likely the low BP. Other less common causes might include hemorrhage or significant blood loss, abnormal magnesium or potassium levels. It is normal for the heart to beat faster when the blood pressure drops. ...Read moreSee 1 more doctor answer
What causes an increase in heart rate when exercising at high intensity? My heart rate went from 180 to 220.
Normal response: But that is too high for you -- your maximum should be no more than 180 and keep it there for about 30 minutes for a proper cardio or aerobic exercise -- and do it regularly 3 times a week -- as you get fitter, your heart rate will lower and it will take longer and higher intensity to get to your maximum heart rate -- don't overstress your heart in a hurry -- it's not a goal but a lifestyle. ...Read more
Bp is 106/80 and heart rate is 103.without any exercise.why heart rate is increased.is it because of tsh haormones or what?
Sneezing: Sneezing can cause a decreased venous return and tachycardia response. ...Read more
Depends: Bp/hr is age dependant and a more specific question is needed to answer. ...Read more
A number of things: It many be that your heart rate increases from factors as simple as drinking too much coffee, or simply being tired or anxious. In some people, a conduction variation in the heart will suddenly bump the rate up. If you have shortness of breath, faintness, dizziness, lightheadedness, or chest/jaw/shoulder pain, get to the ER or call 911. ...Read moreSee 1 more doctor answer
Normal: Normal HR = 60-100 at rest.Get a more detailed answer ›
Yes.: Intraamniotic infections can cause maternal sepsis (headache, weakness, fever, myalgias) and fetal tachycardia - they are even associated with adverse neurological outcomes such as cerebral palsy in rare occasions. Prompt diagnosis and treatment with broad-spectrum antibiotics is likely to prevent major complications. ...Read more
Acidosis.: Non-reassuring fetal heart tones include loss of beat to beat or short term variability. They are commonly used to monitor fetal status and determine timing/mode of delivery although they have an exceedingly high false-positive rate in predicting actual neurological impairment in the infant. They can be due to: acidosis; hypoxia; drugs; infection; sleep cycle; dehydration; anemia; thyroidopathies. ...Read more
Several Causes: Most people with hypertension (85-95%) have a genetic predisposition (primary hypertension). The remainder of people with hypertension have the condition secondary to some other underlying condition such as renal parenchymal disease, renal vascular disease, hyperthyroidism, cushing's syndrome, primary aldosteronism etc. Pregnancy also can cause hypertension in certain women. ...Read more
