EKG Findings
This lethal arrhythmia shows no organized P waves, QRS complexes, or T waves on EKG.
What is ventricular fibrillation
Pharmaceutical options for rate control in a patient with longstanding persistent or recurrent atrial fibrillation?
What is:
Beta-blockers (Metoprolol, Atenolol, Propranolol)
or
Nondihydropyridine calcium channel blockers (Diltiazem, Verapamil)
When all QRS complexes in ventricular tachycardia have the same shape and duration, it is classified as this type.
What is monomorphic ventricular tachycardia?
This severe electrolyte disturbance is associated with QRS prolongation, flattened P waves, and peaked T-waves.
What is hyperkalemia?
Diffuse ST elevation with PR depression is characteristic of this condition.
What is acute pericarditis
The first-line treatment for hemodynamically stable Torsades de Pointes is this intravenous agent
What is IV magnesium sulfate
This type of ectopic beat arises early from the ventricles, creating a wide, bizarre QRS complex without a preceding P wave.
What is a premature ventricular contraction (PVC)?
This electrolyte abnormality is classically associated with the appearance of U waves on the EKG.
What is hypokalemia
This arrhythmia is characterized by an irregularly irregular rhythm with no distinct P waves on EKG.
What is atrial fibrillation
In asymptomatic patients with PVCs and no underlying heart disease, this is the typical management approach.
What is reassurance and observation?
Repolarization abnormality: Pseudo RBBB with ST-segment elevations in V1–V3 and an increased risk of sudden cardiac death define this syndrome.
What is Brugada Syndrome
This electrolyte abnormality, which often coexists with hypokalemia, can exacerbate arrhythmias and may present with prolonged QT intervals. Can cause hyperreflexia, muscle weakness, and tetany.
What is hypomagnesemia?
On EKG, WPW shows this characteristic finding, which represents early ventricular depolarization.
What is a delta wave?
AVRT: Unstable tachycardia with a pulse
What is electrical cardioversion
This is the most common type of paroxysmal supraventricular tachycardia (PSVT), characterized by a narrow complex tachycardia originating from the AV node.
What is AVNRT?
Marked hypercalcemia can present with this EKG finding, which involves the shortening of this specific interval.
What is a shortened QT interval?
