If a myocardial infarct destroyed a portion of the right or left bundle branches what potential change might you see in the ECG?

You can see the M pattern in ECG in place of ORS complex. In case of right bundle branch block, you see the M pattern in lead V one. In case of left bundle branch block, you see the M pattern in lead V six.

The bundle branches are the part of the conduction system which conducts impulses from the atria and into the ventricles. If there is a block in the left bundle branch, this will affect the left ventricle and if there is a block in the right bundle branch, this will affect the right ventricle. ECGs are very complex and a basic understanding of how an ECG works and what they represent is needed before being able to understand bundle branch blocks - but this is the basic changes you will see on an ECG: On an ECG a block in either the right or left bundle branches will be shown as wide QRS complexes as the impulse is having to travel from cell to cell which is a lot slower than if it travels through the conduction pathways. In Left bundle branch block, the impulse is travelling from the right ventricle (which is working normally) to the left ventricle. Therefore lead V1 will be a negative deflection as the impulse is travelling away from that lead and towards V6 (which will therefore be positive). There may also be some notching at the top of the QRS complexes in other leads. In Right bundle branch block, the right ventricle is affected and the impulse is travelling from the left ventricle and then by cell to cell conduction in the right. In a healthy heart, the contraction of the right ventricle is hidden by the QRS complex which represents the left ventricle contracting. However if the right bundle is blocked, the contraction of the right ventricle will be delayed which is shown on the ECG by the 'rabbit ears' appearance of the QRS complex. There will also be slurred S waves in leads I and V6.

Lack of blood to a tissue fed by blocked arteries is called?
Infarct
Does an infarct putrefy?
Generally no, unless blood supply is returned to the area or a supporating bacteria somehow invades the area. One of the more common locations for an infarct is in the kidneys, and the usual chronic result is fibrosis, not putrefaction.
What is a cerebellar infarct?
The word cerebellar refers to the cerebellum. This is also called the Little Brain. The cerebellum, in the back of the brain, controls balance, coordination and fine muscle control (e.g., walking).Damage may cause ataxias (inability to walk in a straight line). An infarct is another name for a small localized area of dead tissue resulting from failure of blood supply. In the case of the brain, a stroke.This person had a stoke in the cerebellum and may have problems with balance and walking.
What is the result of brain infarct on human?
When an infarction happens in the brain that is known as a cerebral vascular accident or more commonly known as a stroke.
What changes can occur on ECG due to coronary artery disease?
The ECG shows ST elevation or depression and pathological Q waves. The pathological Q wave is a sign of an old infarct (heart attack) as the muscle doesn't conduct an impulse at a certain point.
What is medical term for dead myocardial tissue resulting from interrupted blood flow?
The medical term for dead myocardial tissue resulting from interrupted blood flow is myocardial infarction, commonly known as a heart attack.
What is Anteroapical Wall Myocardial?
If your asking about an anteroapical wall myocardial infarct, this refers to a lack of oxygen reaching heart muscle on the front top end of the heart, causing some of it to die. A myocardial infarct is also known as a heart attack, the name just refers to the position of damage.
What is the area of dead tissue within heart muscle?
Anterior myocardial infarction
What is the medical term meaning Area of a tissue that undergoes necrosis following cessation of blood supply?
InfarctionAn infarction is an area of tissue death caused by ischemia.it is called an infarct.
What nutrients needs of myocardial infraction?
the heart requires oxygen and fats to work (energy production), plus (post infarct) amino-acids for growth and repair. The rest of the body still need the regular stuff.
Hypertension-signs and chronic symptoms?
Hypertension is almost always asyntomatic. When the values of arterial pressure are very high, the symptoms may be: headache,malaise, vomiting, or even a myocardial infarct or a cerebral event ( ischemic or hemorrhagic).
What is a bone infarct?
Bone infarct refers to ischemic death of the cellular elements of the bone and marrow.
What is the medical term meaning damage to the heart muscle caused by a thrombus blocking a coronary artery?
Coronary thrombosis can lead to myocardial infarction, or damage to the heart muscle.Myocardial infarct....Myo- means muscle.Cardial refers to the heart.Infarction is the death of tissue due to the lack of blood supply.HL
What can cause sudden cardiac death?
An infarct.
What happens when you have a infarct in your heart?
heart attack
What is meant by infarct?
that is when a pat dies, the term is most frequently used to describe an area of the heart or brain. An infarct is caused by lack of blood flow (perfusion) or trauma.
What is the difference between erythema and hyperaemia?
Erythema is the physical sign of redness of an ectodermal structure like skin or the exocervix. It is caused by Hyperemia, which is the presence of increased blood flow to a particular structure. Erythema is a physical sign, while Hyperemia is a physiologic process. Hyperemia can also occur in other parts of the body like in a myocardial infarct.
