There is growing anecdotal documentation that the increase in circulating volume of blood during pregnancy may sometimes very slightly stretch the heart chambers leaving a vulnerable spot where the heart muscle can self stimulate leading to peri pregnancy ectopics but more pronounced post pregnancy ectopics. Exercise – due to adrenaline – usually in warming up and cooling down period.Things that may stimulate ectopics not necessarily to avoid but to be aware of Glutimate of which MSG is an example, often found in takeaway’s, prepared ready meals and energy bars – particularly with women it seems.Stimulants such as those found in decongestants.Things to avoid which may help minimise ectopics as they are all stimulants It is not uncommon to have runs of these lasting 3 or so beats. After these, normal rhythm is re-established. What you may feelĪ “butterfly” feeling, a fluttering in the throat, followed by a heavy thump or bang in your chest. In no way does this drummer affect the steady one who will continue his rhythm regardless of what his colleague is doing. The second drummer is easily excitable and occasionally in a piece where he should remain silent he cannot resist throwing in the odd beat – an ectopic beat stimulated from the muscle wall. One beats a steady beat, occasionally changing cadence to go faster or slower but the beat remains steady – This is your SA node. If you like an easier example is when you have 2 drummers. The next beat must be stronger than usual to pump the extra accumulated blood out of the chamber. The thumping or pounding is caused by the fact that when there is an ectopic which is not strong enough to clear the chamber of blood, thus the pause before the next beat is usually longer than normal allowing the SA to continue in its routine as normal. This is often accompanied by a feeling that the heart is thumping or pounding in the chest. If a person is aware of the event,and many people who get them are not aware of them at all, the first symptom of an ectopic is usually a feeling that the heart has skipped or missed a beat.
adrenaline stimulates an early contraction of the heart muscle not stimulated by the SA node. The blood from the right ventricle gets pumped to the lungs to be re-oxygenated from our breath, and the blood from the left ventricle goes round the body via the aorta.Īn ectopic (out of place) beat refers to a contraction of the upper heart chamber which occurs before it would be expected. As the electrical impulse is then conducted to the ventricles through a form of ‘junction box’ called the AV node (atrioventricular node), the impulse spreads across the ventricles, causing these muscles to contract and to pump out the blood. This node sends out automatic electrical impulses through the top chamber (the atrium) causing it to contract and pump the blood through a valve into the bottom chamber (the ventricle). You can be brain dead but your heart will still be going strong.Įach normal beat starts with the SA node ( sinoatrial node) which is our natural pacemaker. It does not need us to be aware of its function and it doesn’t use any part of the active brain either. The heart works on a fully independent and automatic system. Honestly speaking – how many of these beats do you really feel? How does it work? It will beat about 100,800 times a day or 705,600 times a week. Your heart is programmed and built to last. Our hearts – the centre of where we perceive life to begin and end. How many of us have been lulled to sleep by first our Mum’s heartbeat and maybe later in life enjoying hearing a new lovers heart beat and then the excitement of seeing and hearing a new baby’s heart beat on the scan. We’ve all heard lubdub, lubdub, the normal, steady, reassuring sound of a heart beat. What is a heart beat anyway and where does this abnormal beat fit in? Whatever you call them, these unusual and unwanted happenings in our chests scare more people into anxiety than most other symptoms. Skipped beats, extra beats, ectopic beats, Premature Atrial contractions PAC’s, Premature Ventricular Contraction’s PVC’s, missed beats, late beats.
