  2. Ventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Ventricular_tachycardia

    Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.

  3. Diagrammatic sign - Wikipedia

    en.wikipedia.org/wiki/Diagrammatic_sign

    A diagrammatic sign or diagrammatic guide sign is a type of guide sign that indicates destinations using a large, map-like illustration of the road layout. The term is most commonly associated with diagrammatic signs installed ahead of forks in controlled-access highways to indicate the destination of each lane.

    However, ventricular tachycardia and ventricular fibrillation remain the most important causes of sudden death following spontaneous restoration of antegrade flow. [6] Prior to the modern practice of percutaneous coronary intervention for acute coronary syndrome , pharmacologic thrombolysis was more common and accelerated idioventricular ...

  5. 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 ...

    en.wikipedia.org/.../Ventricular_tachycardia

    Well, even though we say tachycardia is anything above 100 beats per minute, most patients with ventricular tachycardia experience heart rates as high as 250 beats per minute. 250 beats per minute means the heart’s beating over four times per second, and when the chambers are pumping that fast, they don’t have enough time to even fill with ...

    en.wikipedia.org/wiki/Controlled-access_highway

    The median-side travel lane of the old two-way corridor becomes a passing lane. Other techniques involve building a new carriageway on the side of a divided highway that has a lot of private access on one side and sometimes has long driveways on the other side since an easement for widening comes into place, especially in rural areas.

  9. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    Fascicular tachycardia usually arises from the posterior fascicle of the left bundle branch. They produce QRS complexes of relatively short durations with a right bundle branch block pattern. Tachycardias originating in the anterior left fascicle would lead to right axis deviation. [citation needed]
