Absolute contra indications to exercise stress test : please choose the best answer
1. Ongoing unstable angina
2. Severe symptomatic aortic stenosis
3.Decompensated heart failure
4.Acute aortic dissection
5. All of the above
@n_soumil24010@Doctors_GUILD The author made a caption for this video and asks causes of sudden cardiac death
We don’t know what further happened to this young boy
If he recovered on his own, it may be a syncope ( transient loss of consciousness) or NON sustained VT lasting few seconds
F/U report needed
@hemo_shk GCA/temporal arteritis involving large and medium arteries
Sudden blindness is a dreaded complication
Imaging guided temporal artery biopsy ( due to skip lesions, may be missed)
High dose corticosteroids followed by
Tocilizumab
Vitamin D calcium
@IhabFathiSulima Vanishing tumour: accumulation of fluid (due to heart failure ) in the inter lobar fissure
Which clears up with anti failure treatment and diuretics
Repeat imaging shows no fluid opacity , so gets the name of vanishing tumour
Insulin secreting tumour: insulinoma
Where pro insulin, insulin and c peptide all elevated
While exogenous administration of insulin will cause high insulin but low c peptide levels
Beta cells in pancreas secrete pro insulin which is cleaved into active insulin and c peptide and that’s why all three raised in insulinoma
Exogenous insulin causes high insulin levels only as it doesn’t contain c peptide
Verapamil
Any AV nodal blocking drugs (like beta blockers, digoxin, adenosine,non dihydro pyridine CCB like verapamil,diltiazem) block normal SA>>AV>> Purkinje>> ventricular pathway
Due to above blockade impulses find their way through accessory bypass pathways associated with WPW ( bundle of Kent,Mahaim fibres) are rapidly conducted through them
As there is no inherent delay (as happens at AV node normally) all conducted through by pass tracts bombard the ventricles directly and rapidly leading to rapid VT/VF with circulatory collapse
Drug of choice is procainamide( does not block AVNode)
Procainamide is a class 1 anti arrhythmic prolongs action potential in atrial and ventricular myocardium thus slowing down ventricular response rates
If circulatory collapse urgent sunchronized cardio version
@TrackYourHeart Cardiac tamponade
Echo shows early diastolic collapse of RA
Management: emergency pericardio centesis and drainage: send fluid for ADA,LDH, gram’s stain, culture for TB, fungus, bacterial,cytology
