Sodium Channel Blockers (Class I Antiarrhythmics)
Description
Na channel blockers are Vaughan Williams class I antiarrhythmics. There are three subclasses: Ia, Ib, and Ic. The use of Na channel blockers as local anesthetics is discussed in the discussion of local anesthetics in Chapter 21.

β Antagonists (β-Blockers)
Prototype and Common Drugs
MOA (Mechanism of Action)
To understand β-blockers, you must understand the effects of the adrenergic system and which effects are mediated via β receptors. β-Blockers competitively antagonize the action of catecholamines at β receptors. There are many cardiac and noncardiac consequences of β-blockade. More details on the autonomic nervous system are described in Chapter 3.
Hypertension
where SVR = systemic vascular resistance.
Tachycardia and Arrhythmia
The properties of β-blockers that make them antitachycardics include the following:
