All of the following can be used to treat torsades des pointes (polymorphic ventricular tachycardia with prolongation of QT interval) except: a) Temporary pacing b) Intravenous magnesium c)

Point-of-care handheld echocardiography (Hand held echocardiograph – Representative image) Initially echocardiographs were large machines with poor resolution. Later advances in electronics miniaturized the machines while improving the resolutions.

Heparin should be overlapped with warfarin till the INR is within therapeutic range, with a minimum of four days after initiation of warfarin therapy.

Ventricular interdependence is the term used to describe the dysfunction of one ventricle secondary to a disorder of the other.

A palpable pericardial rub is known as pericardial fremitus. It is due to the friction between the parietal and visceral layers of the pericardium.

Multislice computed tomography for assessing myocardial viability: Iodinated contrast used for CT scanning accumulate in infarcted myocardium similar to what happens with late gadolinium enhanced (LGE) magnetic resonance

Cardiac magnetic resonance (CMR) imaging can be used to assess myocardial viability. Preserved myocardial wall thickness of more than 5.5 mm has a good sensitivity of 95%, but

Positron emission tomography (PET) is usually taken as the gold standard for assessment of myocardial viability. A mismatch between perfusion and metabolism whereby underperfused region of myocardium is

Balanced myocardial ischaemia If all three major coronary branches have similar degree of stenosis, the radionuclide used for perfusion study will have equal uptake in all regions of
