Narrow QRS complexes occur regularly. This tracing suggests either atrial flutter or ventricular tachycardia. It is not atrial flutter, however. If it were, the QRS complexes occurring regularly would ...

Irregular heart rhythms are common in PAH and tied to higher risk of poor outcomes, with right heart changes helping predict ...

Cardiac arrhythmias following myocardial infarction (MI) predict poor outcome. β-blockers are effective ventricular antiarrhythmics and angiotensin-converting-enzyme (ACE) inhibitors can prevent both ...

When atrial flutter is seen with such a slow ventricular response (in this case, 9:1 conduction), there is concern for underlying complete heart block should the patient be restored to normal sinus ...

Atrial flutter is a type of irregular heartbeat, or an arrhythmia. It causes your heart to beat too fast. Atrial flutter doesn't always have symptoms, but it can sometimes have serious consequences if ...

A 67-year-old man with acute anterolateral myocardial infarction had recurrent ventricular fibrillation that required insertion of temporary pacemaker. When a permanent pacemaker was inserted stable ...

Atrial flutter is an abnormal heart rhythm where the upper heart chambers beat too fast, reducing the heart’s ability to pump blood effectively and potentially leading to heart muscle damage, stroke, ...

Atrial flutter is a heart disorder in which the heart beats out of its normal rhythm. The condition is similar to atrial fibrillation (afib) — the most common type of arrhythmia (abnormal heartbeat) — ...
