Will atherosclerosis of the femoral artery affect heart beat and ekg?

Will atherosclerosis of the femoral artery affect heart beat and  ekg?

No: Ekgs measure the electrical activity of the heart. Palpitations ( irregular heartbeats) are also a function of the electrical activity in the heart. Neither of these will be affected by having atherosclerosis in the femoral artery of the leg. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Name a medicine that increases heart rate and the force of heart contraction?

Name a medicine that increases heart rate and the force of heart contraction?

Sympathomimetics: The group name of medications that increases heart rate/contractions (chronotropic) are sympathomimetics. Of these are included caffeine, epinephrine, dopamine, Dobutamine (mostly contraction strength), and many others. ...Read more

Can gas have an impact on the heart such as an irregular heart beat or pressure passing surrounding areas of the heart? Male 21 smoker

Can gas have an impact on the heart such as an irregular heart beat or pressure passing surrounding areas of the heart? Male 21 smoker

Nope: The heart is effectively isolated from the pressures of the bowel, though it can, under the right circumstances be subject to the pressures of the lung. Sorry to hear about the gas though. ...Read more

Does ehlers danlos increase the risk of heart attack caused by vessels and such in the heart collapsing and not letting enough blood through?

Does ehlers danlos increase the risk of heart attack caused by vessels and such in the heart collapsing and not letting enough blood through?

No: Glad to reassure you. It just doesn't. Even Ehlers-Danlos IV, in which the arteries end up very fragile and prone to intractable hemorrhaging, doesn't do this. It just doesn't happen. ...Read more

Can the flow rate on a IV line cause atrial fribulation, which in turn weaken the heart muscle, create clots and flood the lungs.

Can the flow rate on a IV line cause atrial fribulation, which in turn weaken the heart  muscle, create clots and flood the lungs.

IV fluid: Fluid is given through an "IV" (a little tube inserted into a vein) for many reasons: to treat dehydration, to give medicines, & to maintain fluid balance when patients aren't drinking. In some patients if too much fluid is given too quickly it can cause problems including with the lungs. For a detailed review of a particular patient problem, ask a doctor through an inbox consult on HealthTap. ...Read more

Could an internal defibrillator increase the ejection fraction of the heart?

Could an internal defibrillator increase the ejection fraction of the heart?

ICD: An ICD which works only in the right ventricle doesn't do anything positive for EF. A biventricular pacing defibrillator's biV pacing component can cause small increases in EF when pacing as a BiV pacer in a patient whose native QRS duration is over 0.12 sec. ...Read more

Can coronary artery spasm occur during exertion or during intercourse? Or is it at rest only? Can normal coronary arteries spasm or just the atherosclerosis arteries?

Can coronary artery spasm occur during exertion or during intercourse? Or is it at rest only? Can normal coronary arteries spasm or just the atherosclerosis arteries?

Yes, exertional only: Coronary artery spasm usually occurs in normal coronary arteries, not atherosclerosis. Coronary artery spasm causes temporary blockage of the artery during periods of exertion (yes, even intercourse), leading to anginal pain or even an MI (heart attack). When at rest, the coronary artery is open with normal blood flow. A medication called "calcium channel blocker" is given daily as treatment. ...Read more

What are the health consequences of a heart rate of 45-50 BPM during contractions from nuchal cord?

Most likely none: It is quite common for infants to experience a slow heart rate during contractions when mother is pushing. However, if the infant is experiencing slow heart rate early in the labor process it may indicate that the baby is compromised. Most infants can tolerate this without long term damage for a short period of time, but ongoing heart rate drops need immediate evaluation. ...Read more

In heart auscultation the sound coinciding with radial pulse is the sound during the heart's systole, is that correct?

In heart auscultation the sound coinciding with radial pulse is the sound during the heart's systole, is that correct?

First Heart Sound: or S1 is the sound of the atrioventricular valves closing for systole and usually coincides with the radial pulse. S2, (racepinephrine) the second sound is the closing of the aortic and pulmonic valve and indicates diastole. Thanks for trusting HealthTap! ...Read more

During an xray what causes widening of vessels around the heart?

During an xray what causes widening of vessels around the heart?

Various causes: Engorgement is due to volume overload as from congestive heart failure or renal failure. Focal enlargement of a vessel may indicated an aneurysm. Widening of the mediastinum can indicate aortic dissection. Central pulmonary artery prominence can be due to pulmonary hypertension. Poor x-ray technique can cause magnification that is artifactual. I'm not a radiologist but that's a quick answer. ...Read more

What are the chances of survival after a massive heart attack followed by angioplasty that causes a cardiac arrest? Now ef 52%, BP 100/70 and pulse 68

What are the chances of survival after a massive heart attack followed by angioplasty that causes a cardiac arrest? Now ef 52%, BP 100/70 and pulse 68

Yes: There are a lot of variables that determine prognosis like; time from when the heart attack started to when the angioplasty was done the ef -52% is good excercise capacity symptom status it would be important to be on a medical regimen to prevent a recurrence and then to try and go to cardiac rehab. ...Read more

Could heart bypass surgery require opening up of the chest?

Yes: Most CABG procedures still require opening the sternum (breastbone) to some degree. While thorascopic surgery is done, it is not mainstream, and usually requires an access thoracotomy (small incision) for completion. ...Read more
