Second, triggered activity.
A M ThirugnanamGUEST
2:23
After depolarizations that set off extra beats, as in Torsades de Pointes and digoxin toxicity.
A M ThirugnanamGUEST
2:31
And third, re-entry, the commonest mechanism, where an electrical wave travels round a circuit and keeps re-exciting the heart, as in atrial flutter, AV nodal re-entry, accessory pathway tachycardias, and most ventricular tachycardia after myocardial infarction.
A M ThirugnanamGUEST
2:53
Understanding the mechanism helps us understand why certain treatments work, for example, why ablation can cure a re-entrant circuit.
A M ThirugnanamGUEST
7:13
Ventricular fibrillation, chaotic electrical activity with no cardiac output is cardiac arrest.
A M ThirugnanamGUEST
7:22
Sustained ventricular tachycardia, especially in a patient with a previous infarct or cardiomyopathy.
A M ThirugnanamGUEST
7:29
Polymorphic VT, including Torsades de Pointes associated with a long QT.
A M ThirugnanamGUEST
7:36
Pre-excited atrial fibrillation in Wolf-Parkinson-White syndrome, which can degenerate into ventricular fibrillation.

A M ThirugnanamGUEST
25:10
Then comes the most important question: Why did this patient have VT? Is it an old infarct scar, a dilated cardiomyopathy, myocarditis, sarcoidosis, or arrhythmogenic cardiomyopathy, an inherited channelopathy? The answer determines the long-term plan.
Alexander WoodHOST
25:30
Let's talk about Torsades de Pointes and the long QT syndromes.
A M ThirugnanamGUEST
25:35
Torsades de Pointes is a polymorphic ventricular tachycardia in which the QRS complexes appear to twist around the baseline.
A M ThirugnanamGUEST
25:46
It occurs in the setting of a prolonged QT interval, and it is often initiated by a short-long-short sequence, an ectopic beat, a pause, and then a beat that falls on the T wave.
A M ThirugnanamGUEST
26:00
It may terminate spontaneously, causing recurrent syncope or degenerate into ventricular fibrillation.

A M ThirugnanamGUEST
26:30
Because in the intensive care unit, we are surrounded by drugs that prolong the QT: amiodarone, haloperidol, macrolide and quinolone antibiotics, ondansetron, methadone, many antipsychotics, and antifungal agents.
A M ThirugnanamGUEST
26:45
Combine them with low potassium, low magnesium, bradycardia, and a sick heart, and you have the perfect setting for Torsades de Pointes.
A M ThirugnanamGUEST
26:53
Measure the QT from the start of the QRS to the end of the T wave, ideally in lead II or V5, choosing the lead with the longest clear QT.
A M ThirugnanamGUEST
27:03
Then correct it for heart rate.

Cardiac Ventricular Arrhythmias: Diagnosis, Treatment and Management

Oct 11 · 1 Mention

A M ThirugnanamGUEST
3:31
Ventricular tachycardia is called monomorphic when all the complexes look the same, which usually indicates a stable re-entry circuit around a scar or a single focus, and polymorphic when the complexes change continuously, which suggests ischemia, an abnormal QT interval, or a channelopathy.
A M ThirugnanamGUEST
3:57
Torsade de Pointes is a specific form of polymorphic tachycardia associated with a long QT interval.
A M ThirugnanamGUEST
4:05
Ventricular flutter is a very fast sine wave-like tachycardia, and ventricular fibrillation is chaotic electrical activity without any effective contraction, causing immediate cardiac arrest.
A M ThirugnanamGUEST
4:22
There are also special forms accelerated idio-ventricular rhythm, a slow ventricular rhythm of 60 to 120 beats per minute, common after reperfusion in myocardial infarction and usually benign.

Cardiac Antiarrhythmic Drugs: Classification, Mechanisms, Effects and Side Effects

Oct 11 · 1 Mention

A M ThirugnanamGUEST
16:43
But it also blocks sodium channels, calcium channels, and beta adrenergic receptors, so it has actions of all four classes.
A M ThirugnanamGUEST
16:54
Paradoxically, despite marked QT prolongation, it rarely causes Torsades de Pointes, probably because it prolongs repolarization uniformly across the heart wall.
A M ThirugnanamGUEST
17:08
It is effective for almost all arrhythmias, atrial fibrillation, ventricular tachycardia, and in cardiac arrest, and it can be used in patients with heart failure and coronary disease, where many other drugs are contraindicated.
A M ThirugnanamGUEST
17:28
Its pharmacology is unusual.

Management is supportive.
A M ThirugnanamGUEST
40:03
She should be monitored in a coronary care unit for complications, cardiogenic shock, left ventricular outflow tract obstruction from basal hypercontraction, arrhythmias, including QT prolongation and Torsades de Pointes, left ventricular thrombus, and rarely rupture.
A M ThirugnanamGUEST
40:26
If she has outflow obstruction with low blood pressure, inotropes should be avoided, and beta blockers and cautious fluids may help.
A M ThirugnanamGUEST
40:37
Heart failure therapy is used for congestion and anticoagulation if a thrombus is seen.

A M ThirugnanamGUEST
23:27
While aminoglycosides, such as gentamicin, carry a risk of fetal ototoxicity and should be used only when essential with level monitoring, and tetracyclines and fluoroquinolones are generally avoided.
A M ThirugnanamGUEST
23:43
Magnesium sulfate is safe and used for preeclampsia and for some arrhythmias, such as Torsades de Pointes.
A M ThirugnanamGUEST
23:52
Potassium replacement is safe.
A M ThirugnanamGUEST
23:54
For low blood pressure during spinal anesthesia, phenylephrine is commonly used.

Yeah.
speaker_1GUEST
38:18
If the reset takes too long, an early after depolarization can trigger a lethal chaotic arrhythmia called torsades de pointes.
Manaan KarrayHOST
38:26
The ventricles stop pumping effectively and just quiver.
Manaan KarrayHOST
38:29
Without immediate defibrillation, torsades frequently degenerates into ventricular fibrillation and sudden cardiac death.
Manaan KarrayHOST
41:29
The result was a massive documented surge in psychiatric relapse, depressive morbidity and hospitalizations.
Manaan KarrayHOST
41:36
And crucially, there was absolutely no demonstrable reduction in cardiac mortality.
Manaan KarrayHOST
41:41
The actual incidence of torsades de pointes caused solely by citalopram is vanishingly rare.
speaker_1GUEST
41:45
It requires clinical nuance.
