What is Moat common arrhythmia after sinus tachycardia in ICU patient Is - and explain in detail?
the most common arrythmia in an ICU patient is sinus tachycardia followed by atrial fibrilations AFL is a hea rhythm disorder that is similar to the more common A Fib. In AFib, the hea beats fast and in no regular pattern or rhythm. With AFL, the hea beats fast, but in a regular pattern. The fast, but regular pattern of AFL is what makes it special. AFL makes a very distinct "sawtooth" pattern classification : * According to its duration Atrial fibrillation is classified into paroxysmal, persistent or permanent (the three P's). * Paroxysmal atrial fibrillation is self-limiting and sinus rhythm restores spontaneously. Paroxysmal atrial fibrillation lasts for less than 7 days and does not require intervention to conve to a normal rhythm such as electrical or chemical cardioversion. * Persistent atrial fibrillation lasts for greater than 7 days. The term persistent is used when there is a plan to use a rhythm control strategy and return the patient to sinus rhythm. * Permanent atrial fibrillation is present when atrial fibrillation is present 100% of the time for greater than 7 days and there are no interventions planned to restore sinus rhythm. * Typical Atrial Flutter (Common, or Type | Atrial Flutter) * Involves the IVC(Idioventricular Rhythm) & tricuspid isthmus in the reentry circuit. Can be fuher classified based on the direction of the circuit: C/ Anticlockwise Reentry. This is the commonest form of atrial flutter (90% of cases). Retrograde atrial conduction produces: * Inveed flutter waves in leads II, III, aVF * Positive flutter waves in V1 -- may resemble upright P waves * Clockwise Reentry. This uncommon variant produces the opposite pattern: * Positive flutter waves in leads Il, III, aVF * Broad, inveed flutter waves in V1 Ref Harrison 20th edition pg 1431
