To calculate the corrected QT interval (QTc) in patients with atrial fibrillation, you typically use the Bazett's formula: QTc = QT / √(RR interval), where the RR interval is measured in seconds. Due to the irregular heart rate in atrial fibrillation, it can be beneficial to average several RR intervals to obtain a more accurate measurement. The QT interval is measured from the beginning of the Q wave to the end of the T wave on the ECG. It's crucial to ensure that the QT interval is accurately measured in the context of the patient's rhythm and heart rate.
What else can I help you with?
What is an atrial fibrillation?
An atrial fibrillation is a cardiac arrhythmia which involves the upper two chambers of the heart.
What is Albanian word for atrial fibrillation?
as simple as: "Fibrilacion Atrial"
Can sepsis lead to the development of atrial fibrillation?
Yes, sepsis can lead to the development of atrial fibrillation, a type of irregular heartbeat.
Which would produce the most life-threatening condition atrial flutter ventricular flutter atrial fibrillation or ventricular fibrillation?
Ventricular fibrillation, since this pumps blood to the rest of the body.
Where can one find information about atrial fibrillation surgery?
One can find information about Atrial Fibrillation surgery on a number of webpages. StopAfib, Medifocus, and Mayo Clinic are few examples of websites where one can find information about Atrial Fibrillation surgery.

What has the author Francis D Murgatroyd written?
Francis D. Murgatroyd has written: 'Atrial fibrillation for the clinician' -- subject(s): Atrial Fibrillation, Physiopathology, Therapy
What are the major types of arrhythmia?
Atrial Fibrillation, Ventricular tachycardia, Ventricular fibrillation, Supraventricular tachycardia
Implanted treatment to control atrial fibrillation?
Pacemaker:))
How is the QRS complex described in atrial fibrillation?
In atrial fibrillation, the QRS complex is typically described as normal, but irregularly spaced due to the irregular heartbeat caused by the condition.
What is more serious atrial or ventricular fibrilation?
Ventricular fibrillation is more serious than atrial fibrillation because it can lead to cardiac arrest and sudden death if not treated immediately. Atrial fibrillation, while still a serious condition, is generally less life-threatening than ventricular fibrillation.
Should emergency defibrillators be used on patients suffering atrial fibrillation attacks?
If patients with atrial fibrillation experience rapid heart rate (rapid ventricular response) and are hemodynamically unstable (hypotension, altered mental status) then electrical cardioversion is appropriate. Defibrillation is never utilized in atrial fibrillation.
