Atrial flutter EKG examples
Shown below is an electrocardiogram from a middle aged man with palpitations. The patient had a dual chamber pacemaker (Vista) set at a lower rate of 60/min, and upper rate of 100/min. The patient had developed atrial flutter, and the pacemaker was following this with a 3:1 block. The flutter is seen in the second panel where the pacemaker was set to a VVI mode and a rate of 30/min. Note that in the first tracing the pacer spikes are not well seen as the pacemaker is pacing in a bipolar mode.
Shown below is an electrocardiogram of atrial flutter 4:1 block with atrial rate of about 270 and a ventricular rate of 68/min.
Shown below is an electrocardiogram of an alternating 2:1 and 3:1 block.
Shown below is an electrocardiogram of atrial flutter.
Shown below is an electrocardiogram of atrial flutter with variable conduction.
Shown below is an electrocardiogram of a very rare condition with 1:1 atrial flutter.
Shown below is an electrocardiogram of a 2:1 atrial flutter.
Shown below is an electrocardiogram of a 2:1 atrial flutter.
Shown below is an electrocardiogram of a 3:1 atrial flutter.
Shown below is an electrocardiogram of a 4:1 atrial flutter.
Shown below is an electrocardiogram of atrial flutter with right bundle branch block.
EKG below is from an 82 year old man with a history of lung disease and renal failure. At the time of this recording the patient was on Iron, Lasix, and bronchodilators.
The EKG shows a regular rhythm at a rate of 141/min. This patient had been in atrial fibrillation in the past and the rhythm here is probably atrial flutter with 2:1 block although no flutter waves are seen. The QRS duration is widened at 105 ms and the tall R waves in V5 and S waves in V1 and V2 and the ST depression in the absence of digoxin suggest left ventricular hypertrophy. The QRS is too narrow for ventricular tachycardia and the brief R wave in V2 with the clean down-stroke of the V2 S wave argue against a ventricular origin. The patient was placed on digoxin with a slowing of the ventricular rate and a rhythm that was clearly atrial fibrillation and with a QRS with the same morphology.
EKG records below are continuous and from a patient being treated with an external cardioverter/defibrillator for atrial flutter. The patient is under general anesthesia and two shocks were given, the first at 50 joules and the second at 100 joules.
The cardiogram show spontaneous termination of atrial flutter. The flutter waves can be seen deforming the QRS especially in leads II and III.
The rhythm below is atrial flutter with flutter waves seen best in the inferior leads and in leads V1 to V3. The atrial rate is about 250/min. The QRS is wide (>120ms) an there is a tall R' wave in V1 and a shallow S in V6. The axis of the QRS seems normal. The EKG shows a right bundle branch block.
