All About Cardiovascular System and Disorders

Myocardial postconditioning : RISK (reperfusion injury salvage kinase) pathway producing upregulation of prosurvival kinases is thought to mediate it.

Intra aortic balloon pump (IABP): ECG, pressure tracing and monitor screenshot.

Ablation of left sided accessory pathways: 95% success rate, 5% recurrence. Re-ablation deferred for 2 months due to risk of perforation and other factors.

A new pocket-sized echocardiograph is available to aid bedside diagnosis.

Echocardiogram in ostium primum ASD with TR: video, 2-D and colour Doppler images showing the left to right shunt and tricuspid regurgitation.

ECG showing junctional rhythm, anterior and inferior wall infarction.

ECG in left main coronary artery stenosis showing ST elevation in aVR.

Rest and nitroglycerine myocardial viability scan: Rest images obtained after 8 mCi of 99mTc IV. 25 mCi hours later after S/L NTG; rest gated imaging done.

Brugada like ECGs with concave upwards ST elevation are common, most of them do not have any life threatening arrhythmias or a positive family history.

GRACE registry suggested that BMS was better than DES in acute MI situation. But recent data with sirolimus eluting stents show promise.
