Ventricular tachycardia VT Cardiology Board Review Lecture for Exam Preparation

Dr. Samuel J. Asirvatham's lecture on Ventricular Tachycardia (VT) provides a comprehensive review of the topic, covering the definition, mechanisms, diagnosis, and management of VT. The lecture is designed to help cardiology fellows and board-certified cardiologists prepare for certification exams.

VT is defined and its mechanisms are discussed, including re-entry, triggered activity, and automaticity. Re-entry occurs when an electrical impulse recurrently activates the ventricle, while triggered activity and automaticity can lead to abnormal electrical activity.

The diagnosis of VT is covered, including electrocardiogram (ECG) characteristics such as wide QRS complexes, AV dissociation, and fusion beats. The clinical presentation of VT is also discussed, including symptoms and signs.

The management of VT is reviewed, including acute management with cardioversion, anti-arrhythmic medications, and ACLS protocols. Chronic management options are also discussed, including implantable cardioverter-defibrillators (ICDs), anti-arrhythmic medications, and catheter ablation.

Throughout the lecture, Dr. Asirvatham incorporates board-style questions to help reinforce key concepts and prepare learners for certification exams. The lecture provides a comprehensive review of VT, making it an excellent resource for cardiology fellows and board-certified cardiologists preparing for certification exams.

𝘼𝙣𝙩𝙞𝙘𝙤𝙖𝙜𝙪𝙡𝙖𝙩𝙞𝙤𝙣 𝘼𝙛𝙩𝙚𝙧 𝙎𝙩𝙧𝙤𝙠𝙚 in Patient with AF and acute IS/TIA European Heart Association Guideline recommends: • 1 days after TIA • 3 days after mild stroke • 6 days after moderate stroke • 12 days after severe stroke Early anticoagulation can decrease a risk of recurrent stroke and embolic events but may increase a risk of secondary hemorrhagic transformation of brain infarcts. The 1-3-6-12-day rule is a known consensus with graded increase in delay of anticoagulation between 1 and 12 days after onset of ischemic stroke or transient ischemic attack(TIA), according to neurological severity based on European expert opinions. However, this rule might be somewhat later than currently used in a real-world practical setting.

Acute Treatment of Hyperkalemia

Acute Treatment of Hyperkalemia – A Practical, Bedside-Oriented Guide Hyperkalemia is a potentially life-threatening electrolyte abnormality that demands prompt recognition and decisive management. The danger lies not only in the absolute potassium value but in its effects on cardiac conduction, which can rapidly progress to fatal arrhythmias. Acute treatment focuses on three parallel goals: stabilizing the cardiac membrane, shifting potassium into cells, and removing excess potassium from the body. Understanding this stepwise approach helps clinicians act quickly and rationally in emergency settings. Why Hyperkalemia Is Dangerous Potassium plays a key role in maintaining the resting membrane potential of cardiac myocytes. Elevated serum potassium reduces the transmembrane gradient, leading to slowed conduction, ECG changes, ventricular arrhythmias, and asystole. Importantly, ECG changes do not always correlate with potassium levels, so treatment decisions should be based on clinical c...

2025 AHA/ACC Hypertension Guidelines Key points

2025 AHA/ACC Hypertension Guidelines Explained: A Clear Summary for Clinicians and Students Hypertension remains one of the most significant contributors to cardiovascular morbidity and mortality worldwide. With continual refinement of evidence and risk-based strategies, the 2025 AHA/ACC Hypertension Guidelines bring an updated, practical approach that clinicians can use in daily practice. To make learning easier, I’ve created a clean and modern infographic summarizing all major recommendations. You can download it below and use it for study, teaching, or clinical reference.
