The Story of the AV Block Family

The Story of the AV Block Family

Atrioventricular block (AV block) is a type of heart block where the conduction between the atria and ventricles of the heart is impaired and this is their story.

The Story of the AV Block Family

Wife = P Wave     Husband = QRS Complex    Pacer = Counselling 

Normal Sinus Rhythm

The wife (P wave) waits at home for the husband (QRS). The husband (QRS) comes home on time every night.

[PR Interval is less than 0.2 seconds (One large block on the EKG paper), there is one P wave per QRS complex, and the rhythm is regular.]

1st Degree AV Block

The wife (P wave) is waiting at home. The Husband (QRS) comes home late every night, but he always comes home, and it is the same time every night.

[Impulse is held at AV node, and PR Interval is greater than 0.2 seconds, or one large box on the EKG paper.]

2nd Degree Block, Type 1 (“Wenckebach”)

The wife (P wave) is waiting at home. The husband (QRS) comes home later and later every night until one night he doesn’t come home at all.

Note: Husband (QRS) must come home at least 2 nights in a row to see this pattern.

[PR interval will become greater and greater until there will be a dropped QRS complex and there are two consecutive P waves, after which the pattern will restart.]

2nd Degree Block, Type 2

The wife (P wave) is waiting at home. Sometimes the husband (QRS) comes home, sometimes he doesn’t. When he does come home, it’s always at the same time.

Note: This is usually more serious than Type I, and will sometimes require counselling (pacing).

[PR and R to R intervals will remain consistent, but there will be “missing” QRS complexes.]

3rd Degree AV Block

Wife (P wave) is no longer waiting at home. She and her husband (QRS) are now on separate schedules, have no relationship to one another, and are no longer talking. Each spouse has a regular, individual schedule.

Note: This frequently requires Counselling  in the form of a temporary or permanent pacer.

[Atrial depolarisation will continue with P waves in a “ventricular standstill” while the ventricles (QRS) are depolarising in an idioventricular rhythm – both will be regular, but will be uncoordinated.]

Lucozade is no longer as effective at treating hypoglycemia

Lucozade is no longer as effective at treating hypoglycemia

Due to changes in its recipe and a significant reduction in glucose, Lucozade will not be as effective as a treatment for hypoglycemic patients.

Recipe changes to Lucozade Original Energy product line mean it will no longer be as effective at treating hypoglycemic patients – this is due to a 50% reduction in glucose based carbohydrates. Healthcare Professionals should seek guidance from their local specialist team on alternative treatment protocols.

This change applies to all Lucozade Energy Flavours. New products started appearing on shelves in April 2017. However, for a short time, both the new and old recipe will be available.

Previously, 100ml of Lucozade Original contained 17g of carbohydrate; this was reduced to 8.9g in April 2017.

Lucozade is no longer as effective at treating hypoglycemia

According to Diabietes.co.uk, patients who experience a hypoglycemic episode are advised to consume 15-20g of sugar when treating low blood sugar, but this will no longer be equivalent to 100ml of Lucozade.

Lucozade Ribena Suntory, which also makes Ribena and Orangina, among other drinks, is lowering its sugar content by replacing these sugars with low-calorie sweeteners, such as aspartame.

Shift planning is essential for safe care, some people using a piece of paper others have their thoughts well arranged in their head, either way everybody does it.

It also features a small key and area for general notes. Due to limited space we have only included enough room to plan up to eight patients, if you need more we encourage you print doublesided.

We encourage you to make comments or suggestions in the comments section below. The most popular will be implemented in a version 2.
