Acute dyspnea in an older woman, is it OMI?
Written by Willy FrickA woman in her 90s with a history of end stage renal disease and complete heart block status post dual chamber pacemaker presented from home with acute onset dyspnea. ECG is shown below.What do you think?The ST and T wave abnormalities jump off the page, but let ' s set that aside just for a moment to review the tracing systematically. The rate is 60 (and remember, slower heart rates are often seen in OMI). Close inspection revealsventricular pacing spikes, best seen in aVL. Many ECG readers will not comment any further on rhythm once ventricular pacing has been identified, but it...

How a ruptured spleen saved a life
Of the many thousand operations I did in my surgical career, most were life-improving rather than life-saving. To me, life-saving implies immediate or imminent risk of death: gunshot wounds, stabbings, gastrointestinal bleeding or perforations, punctured lungs, and cracking a chest in the ER for a stab wound to the heart. Potentially life-saving but less dramatic

What is 3D Rotational Angiography?
Some experiments of rotational angiography were going on decades back. Sometimes it would even end up in ventricular fibrillation due to prolonged injection of contrast which deprives myocardium of oxygenated blood. 3D rotational angiography is not that old technique, but a novel technology which can create a volumetric data set of contrast-enhanced CT like images with excellent visualization of soft tissues and airway, with spatial resolution even better than multi-detector CT or cardiac magnetic resonance imaging [1]. The single plane C-arm flat panel detector which we see in most cathlabs now-a-days, rotates around the ...

What is Ultrafast Ultrasound Imaging?
Ultrasound techniques currently used in echocardiography uses frame rates from 30-150 frames/s. This limits its temporal resolution for very short lived events, especially in pediatric and congenital heart disease with faster heart rates compared to adults [1]. While conventional ultrasound uses focused beam transmission, ultrafast ultrasound uses unfocused plane-wave ultrasound which can result in very high temporal resolution with frame rates up to 100 times faster [2]. Potential lower spatial resolution while using plane-wave is taken care of by using multiple plane-waves transmitted at slightly different angles with a ...

Why the Low Weight Group Exhibits Worse Outcomes in Some Epidemiological Studies
In this study, we first explored the association between WC, WHtR, and WWI change patterns and multimorbidity. WC and WHtR are considered to be important anthropometric indicators of abdominal obesity. Previous studies have suggested that WC and WHtR can reflect body fat percentage accurately and play an important role in predicting some chronic diseases, such as cardiovascular disease and metabolic syndrome. The pathway may explain that abdominal obesity significantly increased plasma triglycerides, low density lipoproteins, and very low density lipoproteins, which have been shown to increase the risk of adverse outcomes ...

A young man with persistent palpitations
Written by Pendell MeyersA teenager was playing basketball when he suddenly developed palpitations and lightheadedness. He presented soon afterward at the Emergency Department with ongoing symptoms. Mentation and blood pressure were normal. He had no chest pain or shortness of breath. Heart rates on the monitor fluctuated from 180-250 bpm.Here is his triage ECG:What do you think?The ECG shows an irregularly irregular polymorphic wide complex rhythm, with some R-R intervals as short as approximately 220 msec or even less. But it is not disorganized enough to be polymorphic ventricular tachycardia. The rhythm is therefo...

Predicting myocardial viability from surface ECG following MI
Once upon a time, long, long ago, cardiologists used to be worried about akinetic segments, scars, dead tissue, and Q waves before attempting revascularization by either PCI or CABG. Now, the concept of myocardial viability has become a cliché ( rather demeaning) at least within the cath labs. Currently ,we follow a self administered whip . Every post-MI patient should be considered for revascularization as a default strategy irrespective of the level of dysfunction or scarring .This can happen either in the IRA territory or non-IRA territory or both.
This strategy is now dis-armed with fresh evidence in the form ...

Wednesday Bible Study: The show is about nothing
The next three psalms are just not very interesting. The first amounts to a curse against the singer ' s unspecified and undescribed enemies, who he is confident God will shoot with an arrow. The second is a standard song of praise, giving God credit for nature and what it offers. The third is more praise for God and a pledge to keep on worshiping and sacrificing. There isn ' t much to say about these, except that they seem to fulfill the function that songs do today in religious services, to remind people of what they are supposed to believe and deepen their investment. Of course these beliefs are contradictory -- God wil...

Allostatic Load as a Correlate of Aging
Allostatic load is the concept of wear and tear on the body that emerges from stresses via overactivation of the neuroendocrine system. Causative stresses can range from starvation to psychological stress to a high burden of age-related dysfunction. At some point reactions to stress that are compensatory tip over into being themselves damaging. Thus one could expect allostatic load to correlate with degenerative aging and risk of mortality to at least some degree. In practice, however, there is little agreement on how to measure allostatic load, particularly in human patients, which makes it hard to compare results from st...
