Supraventricular tachycardia (SVT) encompasses several arrhythmias, including atrioventricular nodal reentrant tachycardia (AVNRT). This comprehensive episode combines an overview of SVT with a focused review of AVNRT, connecting ECG recognition, reentry mechanisms, and clinical management.
***Of note, this episode has a lot of visual drawings and may not be optimal to listen to without seeing the video as well
Topics covered include:• Supraventricular tachycardia terminology and classification• AVNRT as a mechanism of paroxysmal SVT• Atrioventricular nodal physiology and reentry• Fast and slow AV nodal pathways• Recognition of regular narrow-complex tachycardia• P-wave visibility and relationships to the QRS complex• ECG features that support AVNRT recognition• Differential diagnosis of supraventricular tachycardia• Assessment of symptoms and hemodynamic stability• Vagal maneuvers and adenosine considerations• Synchronized cardioversion considerations• Recurrent episodes and catheter ablation
The discussion connects the electrical mechanism of tachycardia with its ECG appearance and management, emphasizing the distinction between the broader category of SVT and the specific mechanism of AVNRT.

Transjugular intrahepatic portosystemic shunt (TIPS), esophageal variceal bleeding, and hepatic encephalopathy are closely connected through the physiology of portal hypertension and portosystemic shunting. This cirrhosis masterclass brings together comprehensive reviews of all three topics, examining their mechanisms, clinical presentation, and management considerations.
Topics covered include:• Portal hypertension and portosystemic circulation• TIPS anatomy, mechanism, and hemodynamic effects• Clinical indications and patient selection considerations• Esophageal varices and the mechanisms of variceal bleeding• Evaluation and management principles for acute variceal hemorrhage• The role of TIPS in managing variceal bleeding• Hepatic encephalopathy pathophysiology and clinical presentation• Portosystemic shunting and ammonia metabolism• Recognition of precipitating factors for encephalopathy• TIPS-associated hepatic encephalopathy• Treatment principles and monitoring considerations• Balancing portal decompression with encephalopathy risk
The discussion connects complications of cirrhosis with the physiologic effects of TIPS, emphasizing how changes in portal blood flow influence both bleeding control and encephalopathy.

#341 PEEP Physiology Explained: Alveolar Recruitment, Compliance, Oxygenation & Hemodynamics
Positive end-expiratory pressure (PEEP) influences alveolar recruitment, respiratory system compliance, gas exchange, and cardiovascular function. This deep dive examines the physiology of PEEP, connecting its effects on lung mechanics and oxygenation with venous return, right ventricular function, and cardiac output.
Topics covered include:• Definition and physiologic purpose of PEEP• End-expiratory lung volume and alveolar stability• Alveolar recruitment versus overdistension• Pressure-volume relationships and respiratory system compliance• Effects on ventilation-perfusion matching and pulmonary shunt• Oxygenation response and its limitations• Relationships between PEEP, plateau pressure, and driving pressure• Airway pressure, pleural pressure, and transpulmonary pressure• Effects on venous return and cardiac filling• Pulmonary vascular resistance and right ventricular afterload• Left ventricular loading and cardiac output• Balancing pulmonary benefits with hemodynamic consequences• Physiologic considerations when assessing changes in PEEP
The discussion integrates respiratory and cardiovascular physiology to explain why the response to PEEP varies with lung recruitability, respiratory mechanics, and the underlying hemodynamic state.
