Heart Attack (Definition)

A life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more

Does a "Normal ECG" report indicates there is nothing like LBBB or past heart attack, stroke or cardiac attack?

Does a "Normal ECG" report indicates there is nothing like LBBB or past heart attack, stroke or cardiac attack?

ECG not great.: While certain things, like a LBBB, would be evident and obvious on an ECG, other things, like previous heart attacks, or more importantly the risk for a future heart attack, may be frustratingly absent from a resting ECG. Echocardiogram and stress test may be more useful cardiac tests for risk stratification. ...Read more

For 58+ F, can presence of LBBB in ECG be indicative of any previous heart attack or stroke? How risky is it for future heart health?

For 58+ F, can presence of LBBB in ECG be indicative of any previous heart attack or stroke? How risky is it for future heart health?

Absolutely, LBBB is: A result of endocardial muscle damage/infarction of the Perkinje fibers & surrounding muscle. Endocardial muscle (because heart contraction blocks capillary flow during each beat) is always most susceptible to ischemic damage (heart attack) yet least reflected on surface EKG other than by elongation of the QRS duration. Thus, a block; QRS duration beyond 80 msec=most sensitive sign of heart attack. ...Read more

My Dad: heart attack 2.5 yrs ago LBBB AS inoperable, 90% blockage in 3 valves 87yrs old Now severe cough when eating, makes him shake. Prognosis?

My Dad: heart attack 2.5 yrs ago LBBB AS inoperable, 90% blockage in 3 valves 87yrs old
Now severe cough when eating, makes him shake. Prognosis?

Dad 85 CAD etc: Sorry to hear about your Dad's problems. Only his physician can give an estimate of his long term prognosis.
The issues he suffers from run in families and thus in your family tree. You cannot change your family history but you do not have to repeat it. Learn to feed the roots of your family tree to avoid getting his problems. I would consult with your Dr to see how to hand other factors in you. ...Read more

Can I prescribe beta blockers in post-coronary artery bypass surgery with LBBB patient?

Can I prescribe beta blockers in post-coronary artery bypass surgery with LBBB patient?

Yes: Beta blockers are strongly indicated in a post CABG patient. The vast majority of patients with a left bundle branch block (lbbb) will tolerate them well. If there are other arythmias (second degree heart block etc) much more care would need to be taken. ...Read more

What can cause a cardiac arrest in a bulimic?

What can cause a cardiac arrest in a bulimic?

Electrolytes: Bulimia lends itself to upsetting the normal chemistry in the blood which is needed to normal functioning of the heart. Not allowing the body to absorb nutrients prevents having the needed sodium and potassium levels. When this balance is off the heart may go into a toxic rhythm leading to death. ...Read more

Does hypoxia by itself lead to cardiac arrest?

Does hypoxia by itself lead to cardiac arrest?

Potentially: Hypoxia means an inadequate amount of oxygen in the blood. Is can lead to vital organs not receiving enough oxygen to survive. If the heart is starved for oxygen this can lead to ischemia or heart cell death which can cause either failure or an abnormal rhythm which leads to a cardiac arrest. ...Read more

Does sudden cardiac arrest happen in children?

Very rarely: Primary cardiac arrest (not related to choking, drowning, etc) is exceedingly rare in children but can happen. Structural problems in the heart that are present at birth can predispose to lethal rhythm problems. This is one of the arguments made to place aeds (automatic external defibrillators) in schools and gymnasiums. ...Read more

Can infants and children have a cardiac arrest?

Can infants and children have a cardiac arrest?

Yes: But usually for different etiologies (causes).
Most children and infants will have a cardiac arrest if they do not get enough air (oxygen) and this will cause the heart rate to decrease to a point where the heart can stop (systole) or go into an abnormal rhythm. Also, cardiac defects or anatomic abnormalities from birth can do this too. The best treatment is CPR and call 911. ...Read more
