  3. Sinus bradycardia - Wikipedia

    en.wikipedia.org/wiki/Sinus_bradycardia

    Rhythm strip of sinus bradycardia at 50 bpm. Sinus bradycardia is commonly seen in normal healthy persons and athletes in the absence of pathophysiological diseases or conditions. [1] Different factors or etiologies could lead to the dysfunction of the sinus node, causing a malformation or prolongation of the impulse. In terms of ...

  4. Left axis deviation - Wikipedia

    en.wikipedia.org/wiki/Left_axis_deviation

    The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.

  5. Sinus rhythm - Wikipedia

    en.wikipedia.org/wiki/Sinus_rhythm

    A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1] It is necessary, but not sufficient, for normal electrical activity within the heart. [2] On the electrocardiogram (ECG), a sinus rhythm is characterised by the presence of P waves that are normal in morphology. [2]

    This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: Two images together forming a two period ECG with RR-interval between two R waves .

  8. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    Rhythm interpretation is an important part of healthcare in Emergency Medical Services . Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia, atrial arrhythmia, ventricular arrhythmia.

  9. Third-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/Third-degree_atrio...

    This is known as an escape rhythm. Since this accessory pacemaker also activates independently of the impulse generated at the SA node, two independent rhythms can be noted on the electrocardiogram (ECG). The P waves with a regular P-to-P interval (in other words, a sinus rhythm) represent the first rhythm.
