For those with diabetes and congestive heart failure (or acute lung edema), their sugar control should be done with insulin instead of oral hypoglycemic agent,...
ATP sensitive potassium channels were discovered in a variety of tissue including pancreatic beat cells, skeletal muscle, smooth muscle, cardiac myocytes, as...
To differentiate wide QRS tachycardia as VT or VT, which one of the following do you think is most incorrest?<br>a) inconstant pulse tension: favor VT<br>b)...
How to improve the D/D of wide QRS tachycardia?<br>In my opinion,<br>a) check pulse tension: if wane-wax, VT<br>b) check if frog sign positive: VT<br>c) ...
Verapamil may terminate wide QRS tachycardia with the following morphology EXCEPT:<br>a) positive concordance<br>b) negative concordance<br>c) RBBB with left...
The following agents are considered as the drug of choice for prevention of atrial fibrillation recurrence in patients with different cardiovascular ...
Do you know how to match the two panels?<br><br>1) left-sided Kent 2) right-sided Kent 3) MAT 4) atrial flutter<br><br>a) post mitral commisurotomy<br>b) ...
Experimental studies have shown that administration of nonsteroidal anti-inflammatory drugs (NSAIDs) to susceptible individuals can lead to the development of...
Antiplatelet agent is the drug of choice for those with acute coronary syndrome. De you know that you have many other choices besides aspirin?<br><br>1) ADP...
The beneficial and harmful effects of nonsteroidal anti-inflammatory drugs (NSAIDs) are related primarily to their inhibition of prostaglandin synthesis. ...
Patients with chest pain typical of myocardial ischemia who have angiographically normal coronary arteries are often referred to as having cardiac syndrome X....
The GP IIb/IIIa inhibitors have been shown in several clinical trials to be effacious as platelet inhibitors in countering the deleterious effects of ...
GP IIb/IIIa :glycoprotein IIb-IIIa receptors---the finalcommon pathway for platelet activation and aggregation. Thus inhibition of these receptors more ...
Recently, there is someone who addresses the possible benefits of percutaneous renal angioplasty (PTA) in the management of patients with renal artery stenosis...
Thank you for your reply!<br>GP IIb/IIIa means glycoprotein IIb/IIIa. What are IIb and IIIa? <br>The glycoprotein is a member of integins family. Integrins are...
I was surprised that some physicians still did not know that what the baseline is when defining ST deviation (either ST depression or ST elevation) when I was ...
Among patients with congestive heart failure, men are more likely than women to undergo a selected evaluation for coronary artery disease, while women are more...
Canadian defibrillator study (CIDS) shows nonsignificant reduction in death. Treatment of patients at high risk for arrhythmic death due to ventricular ...
Dear Allen,<br><br>I surely agreed with you that echocardiography is decisive in the D/D of VT or PSVT + aberrancy, but one cannot deny that echo is too...
Thank you for your opinion. Echocardiography is certainly technique-dependent, but the same condition occurs in other ultrasound examination such as abdominal ...
First degree AV block can not cause bradycardia itself except that the underlying rhythm is bradycardia such as sinus bradycardia. If you meet a patient with ...
To my knowledge, inconstant pulse tension, frog sign, AV dissociation, capture beat, fusion beat, and concordance of QRS axes over the procordial leads all...
Does PTA work in HTN patients with renal artery stenosis?<br>Or should we address the question like this: Does PTA work in HTN "Taiwanese" patients with renal ...
My teacher also taught me that concordance favors the diagnosis of VT. However, it is not the true situation. Positive concordance (which means all QRS vectors...
Fully agreed with you.<br>It is stated on page 511 in "The Heart 7th ed" that:<br><br>"A dominant monophasic R in all chest leads - provided preexcitation can ...
Is 1st degree AVB a cause of syncope?<br>Yes.<br><br>During first degree AV block, every atrial impulse conducts to the ventricles, producing a regular ...
