Study Notes

Echocardiography: A Comprehensive Overview

Echocardiography is the primary imaging modality for evaluating cardiac structure and function in most clinical conditions.
It is quick, minimally invasive, and provides clinically relevant data at a relatively low cost.
Echocardiography provides detailed information on cardiac structure, including chambers, valves, and function.
Different types of echocardiography include trans-thoracic, trans-oesophageal, stress, contrast, and 3D echocardiography.
Echocardiography involves using ultrasound waves to create images.
Echogenicity of tissue refers to its ability to reflect or transmit ultrasound waves.
Different types of transducers/probes include linear-array, curved-array, and phased-array transducers.
Linear-array transducers produce flat superficial surface images and are designated by transmit frequency.
Curved-array transducers produce curved superficial surface images and are designated by transmit frequency.
Phased-array transducers create sector image formats and are useful for limited acoustic access areas.
The "PART" maneuver (Pressure, Alignment, Rotation, Tilting) is used for ultrasound probe manipulation.
Proper orientation of the ultrasound image is essential for accurate identification of anatomical structures.

Antidysrhythmic Drug Classes and Clinical Uses

The Vaughan Williams Classification system categorizes antidysrhythmic drugs into four main classes: sodium channel blockers (subdivided into classes 1a, 1b, and 1c), beta blockers (class 2), potassium channel blockers (class 3), and calcium channel blockers (class 4).
Sodium channel blockers, such as disopyramide, lignocaine, and flecainide, bind to voltage-gated sodium channels and inhibit action potential propagation, working more effectively against abnormal high frequency activity.
Class 1a drugs like disopyramide are used for ventricular dysrhythmias and prevention of atrial fibrillation triggered by vagal overactivity.
Lignocaine, a class 1b drug, is administered intravenously and is used for the treatment and prevention of ventricular tachycardia and fibrillation during and immediately after myocardial infarction.
Flecainide, a class 1c drug, suppresses ventricular ectopic beats and prevents paroxysmal atrial fibrillation and recurrent tachycardias associated with abnormal conducting pathways.
Beta blockers, including sotalol, bisoprolol, and atenolol, block β-1 receptors, slowing the heart and decreasing cardiac output, and are used to reduce mortality following myocardial infarction and prevent recurrence of tachycardias provoked by increased sympathetic activity.
Potassium channel blockers, exemplified by amiodarone, prolong the cardiac action potential and refractory period and are used in tachycardia associated with the Wolff-Parkinson-White syndrome and other supraventricular and ventricular tachyarrhythmias.
Calcium channel blockers such as verapamil and diltiazem block cardiac voltage-gated L-type calcium channels, reducing the force of contraction of the heart and are used to prevent recurrence of supraventricular tachycardias and reduce the ventricular rate in patients with atrial fibrillation.
Adenosine, an unclassified drug, is used to terminate supraventricular tachycardias by hyperpolarizing cardiac conducting tissue and slowing the heart rate.
Digoxin, also unclassified, increases vagal efferent activity to the heart, reducing heart rate and conduction velocity through the atrioventricular node, and is used in heart failure but can be toxic at high concentrations.
The Vaughan Williams Classification system may need updating to include additional classes such as HCN (pacemaker) Channel Blockers (Class 0) and potential upstream target modulators like statins and ACE inhibitors (Class VII).
Potential learning outcomes include understanding the mechanisms of action and clinical uses of different classes of antidysrhythmic drugs and the potential need for updates to the existing classification system to incorporate new drug classes and
