Sawtooth Ecg

The ECG criteria to diagnose atrial flutter are discussed including clockwise and counterclockwise, typical vs atypical atrial flutter, and different conduction patterns This produces a characteristic "sawtooth" pattern of the P waves different from atrial fibrillation, in which the atrial rate is so fast that the P waves are not .Narrow complex tachycardia; Regular atrial activity at ~300 bpm; Flutter waves "saw-tooth" pattern best seen in leads II, III, aVF may be more easily spotted by turning the ECG upside down! Flutter waves in V1 may resemble P waves; Loss of the isoelectric baseline. Fixed AV blocks. Ventricular rate is a .Atrial flutter. {{{locatieafbeelding}}}. Atrial rate, 250-350 bpm. Ventricular rate, 75-150bpm 3::1 block . Regularity, regular sometimes changing block . Origin, atrial SVT . P-wave, negative sawtooth in lead II. Effect of adenosine, temporary reduced AV conduction eg 4:1 . Example ECG: {{{example}}}..

    During atrial flutter the atria depolarize in an organized circular movement. This is caused by re-entry. The atria contract typically at around 300 bpm, which results in a fast sequence of p-waves in a sawtooth pattern on the ECG..

    If the P waves are about 300 per minute, and there is a 3:1 block, then the ECG will have a characteristic saw-tooth appearance if atrial flutter is associated with a .

    Atrial Flutter with 2:1 Block. There is a narrow complex tachycardia at 150 bpm. There are no visible P waves. There is a sawtooth baseline in V1 with flutter waves visible at 300 bpm. Elsewhere, flutter waves are concealed in the T waves and QRS complexes. The heart rate of 150 bpm makes this flutter with a 2:1 block..

    Atrial flutter. A characteristic 'sawtooth' or 'picket-fence' waveform of an intra-atrial re-entry circuit usually at about 300 bpm. This lady was taking rather too much digoxin and has a very slow ventricular response..
