  2. Electrical alternans - Wikipedia

    en.wikipedia.org/wiki/Electrical_alternans

    Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...

  3. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    The electrical axis of the heart is the net direction in which the wave of depolarization travels. It is measured using an electrocardiogram (ECG). Normally, this begins at the sinoatrial node (SA node); from here the wave of depolarisation travels down to the apex of the heart. The hexaxial reference system can be used to visualise the ...

    en.wikipedia.org/wiki/AV_nodal_reentrant_tachycardia

    If the symptoms are present while the person is receiving medical care (e.g., in an emergency department), an ECG may show typical changes that confirm the diagnosis i.e., QRS duration <120 ms, unless a heart block is suspected. [7] If the palpitations are recurrent, a doctor may request a Holter monitor (portable, wearable ECG recorder). Again ...

    The clinician must therefore be well versed in recognizing the so-called ECG mimics of acute myocardial infarction, which include left ventricular hypertrophy, left bundle branch block, paced rhythm, early repolarization, pericarditis, hyperkalemia, and ventricular aneurysm.

  6. P wave (electrocardiography) - Wikipedia

    en.wikipedia.org/wiki/P_wave_(electrocardiography)

    P-wave changes in left and right atrial hypertrophy. Bifid P waves (known as P mitrale) indicate left-atrial abnormality - e.g. dilatation [6] or hypertrophy. [1] If at least three different shaped P waves can be seen in a given ECG lead tracing, this implies that even if one of them arises from the SA node, at least two others are arising ...

  7. Left axis deviation - Wikipedia

    en.wikipedia.org/wiki/Left_axis_deviation

    Normal variation causing LAD is an age-related physiologic change. Conduction defects such as left bundle branch block or left anterior fascicular block can cause LAD on the ECG. Pre-excitation syndrome as well as congenital heart diseases such as atrial septal defect, endocardial cushion defects can also cause LAD on ECG.

  9. 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]
