- A patient has heart murmur associated with mitral valve. How will this affect the ECG? Explain.arrow_forward21) Female,35 years old. She came to the clinic because of persistent precordial pain for 2 days. Physical examination: frictional sounds can be heard in the fourth rib space on the left side of the sternum,which can still be heard after holding the breath. The ECG suggests bow-dorsal downward elevation of the ST seament in the conventionai leads. What is her most likely clinical diagnosis? A Acute myocardial infarction() B Variant angina C Acute pleurisy D Acute pericarditis E Acute pulmonary embolismarrow_forwardIndicate which of the following sentences is true in heart failure caused by stenosis of the mitral valve. Group of answer choices 1)Anytime a valve is stenotic, the L atrium must generate a greater force than normal to attempt to move blood through the narrowed opening. This decreases the workload on the heart, eventually leading to an inoperative muscle. 2)Anytime a valve is stenotic, the L atrium must generate a greater force than normal to attempt to move blood through the narrowed opening into the L ventricle. This increases the workload on the heart, eventually leading to its weakening and failing. 3)Anytime a valve is stenotic, the R atrium cannot generate greater force than normal to attempt to move blood through the narrowed opening, and it fails. 4)Anytime there is valve regurgitation, the heart must generate a greater force than normal to attempt to move blood through the narrowed opening into the ventricle. This increases the workload on the heart,…arrow_forward
- Heart attack Atherosclerosis Ischemia Myocardial infarction Congestive heart failurearrow_forwardIn the image attached help me locate the anterior ventricular artery and draw a thrombosis in that artery and then shade the area of the heart that would experience a myocardial infarction. Thanksarrow_forwardIndicate the correct order of the sequence of events occurring during congestive heart failure. Order the sentences (Hint: End with "g") This question is a great summary of what happens, in steps, in congestive heart failure. a. narrowed bicuspid valve makes the L atrium pump harder in order to "push" blood into the L ventricle through an opening that is too narrow. b. pressure of the extra, backed up blood in the lung creates pressure in the capillaries that begin to leak fluid into the lung. c. extra "left-over" blood in the atrium that has not descended into the ventricle after a beat has nowhere to go. d. congenital heart defect causes a narrowed bicuspid valve e. not all blood gets "pushed" from the L atrium to the L ventricle during a regular heart beat f. blood that backed up in the L atrium with nowhere to go backs up further, into the pulmonary veins and eventually into the lung g. the patient gets less oxygen with each breath, feels tired all the time and is…arrow_forward
