The major factor underlying atrial flutter symptoms is the ventricular response rate.If the atrial rate is 300 and the atrioventricular (AV)conduction ratio is 4:1,the ventricular response rate is 75 beats/min and should be well tolerated.If,on the other hand,the atrial rate is 300 beats/min but the AV conduction ratio is 2:1,the corresponding ventricular rate of 150 beats/min may cause angina,acute heart failure,or other signs of cardiac decompensation.
