Dyspnoea, dizziness and dysrhythmia in a middle-aged patient

Heart BMJ

The two-dimensional (2D) transthoracic echocardiogram revealed left ventricular ejection fraction of 40%. N-terminal pro Brain Natiuretic Peptide(NT-proBNP)(ECLIA, Roche) was elevated at 1360 pg/mL. The chest X-ray showed an enlarged left cardiac border with calcification.

WHAT EXACTLY IS AN ARRHYTHMIA?

Dr. Sanjay Gupta

In that sense, the term dysrhythmia is preferable because it does literally translate as a disturbance in normal rhythm which is exactly what it is meant to describe. Any unsolicited disturbance of the rate or rhythm can be termed a dysrhythmia and result in the heart beating less efficiently but only for the duration of the dysrhythmia.

A Child with Blunt Trauma

Dr. Smith's ECG Blog

Blunt cardiac injury my result in : 1) Acute myocardial rupture with tamponade 2) Valve rupture (tricuspid, aortic, mitral) 3) Coronary thrombosis or dissection (and thus Acute MI) from direct coronary blunt injury 4) Dysrhythmias of all kinds. Localized bleeding from contusion could cause hemopericardium even without rupture.

Torsade in a patient with left bundle branch block: is there a long QT? (And: Left Bundle Pacing).

Dr. Smith's ECG Blog

Because she has cardiomyopathy and ventricular dysrhythmias, the pacer included an Implanted Cardioverter-Defibrillator (ICD) Echo 6 days later after CRT: Normal estimated left ventricular ejection fraction. The septum is punctured with the active fixation screw of the lead - so essentially you bore the septum with the screw helix."

The three things that can go wrong with the heart

Dr. Sanjay Gupta

With this test, an echocardiogram is done at rest to study the pumping ability of the heart. The heart is an electrical organ and occasionally the electrics can choose to malfunction and the patient may develop a heart rhythm disturbance or a dysrhythmia such as AF or SVT or VT. You can only diagnose it in retrospect.

60-something with wide complex tachycardia: from where does the rhythm originate?

Dr. Smith's ECG Blog

Inferior MI results in scar tissue which is a likely source of a re-entrant ventricular dysrhythmia. Echocardiogram: Estimated left ventricular ejection fraction, lower limits of normal; 45-50%. Here is the post-cardioversion ECG: There is sinus with RBBB There are inferior Q-waves suggesting old inferior MI.

An athletic 30-something woman with acute substernal chest pressure

Dr. Smith's ECG Blog

Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. These are reperfusion T-waves (the same thing as Wellens' waves) Echocardiogram Regional wall motion abnormality-distal septum and apex. Again, cath lab was not activated. What does this troponin level mean?
