EKG / ECG monitor simulation of Normal Sinus Rhythm at a heart rate of 62bpm.

Normal Sinus Rhythm (NSR)

Normal Sinus Rhythm (NSR) is the expected rhythm on an EKG in patients without pathophysiology. It represents the normal electrical cycle of the heart, which was discovered once a tool capable of detecting it was invented: the electrocardiogram (EKG/ECG).

EKG / ECG monitor simulation of Sinus Bradycardia at a heart rate of 42bpm.
ekg

Sinus Bradycardia

Sinus Bradycardia is a Sinus Rhythm with a rate less than 60bpm and is otherwise identical to Normal Sinus Rhythm (NSR). This slow rate results in long RR Intervals on the EKG tracing and fewer complexes per minute.

EKG / ECG monitor simulation of Sinus Tachycardia at a heart rate of 130bpm.

Sinus Tachycardia

Sinus Tachycardia is a Sinus Rhythm with a rate greater than 99bpm and is otherwise identical to NSR. This fast rate results in short RR Intervals on the EKG tracing and more frequent complexes per length.

 Supraventricular Tachycardia (SVT) EKG / ECG monitor capture (software generated.)

Supraventricular Tachycardia (SVT)

Supraventricular Tachycardia is a category rather than specific rhythm. SVTs are tachycardic rhythms which originate above the ventricles.

EKG monitor simulation of Atrial Fibrillation at a rate of 60bpm.
ekg

Atrial Fibrillation

Atrial fibrillation is the most common dysrhythmia seen clinically. It is characterized by an irregular rhythm and fibrillation waves on the EKG baseline.

Simulated EKG monitor capture of an AV Pacemaker with a heart rate of 68bpm.

Atrio-Ventricular Pacemaker

AV Pacemakers can completely replace the pacemaking function of the heart. Artificial spikes before each wave of an EKG are indicative of implanted pacemaker activity.

Ventricular Tachycardia (VT) EKG / ECG monitor capture (software generated.)
ekg

Ventricular Tachycardia

Ventricular Tachycardia (VT) is a potentially lethal rhythm in which the ventricles have taken over pacemaking at a tachycardic rate. VT is characterized by wide QRS complexes at a rapid rate and regular rhythm.

EKG monitor simulation of Ventricular Fibrillation (VF).
ekg

Ventricular Fibrillation

Ventricular Fibrillation is a lethal rhythm defined by disorganized electrical activity of the ventricles. On the EKG it creates random, erratic deflections with no discernible pattern.

EKG monitor simulation of Asystole.
ekg

Asystole

Asystole is the absence of electrical activity. It creates a nearly flat EKG tracing and is considered cardiac arrest.
