Inappropriate Sinus Tachycardia
The normal heartbeat is generated just like clockwork by electric signals sent out from a natural pacemaker known as the sinus node. Normal individuals have heart rates of between 60-90 beats per minute. This is actually slower than the natural pacemaker of the heart, partly because there is the slowing influence of the nervous system…
PVC Heart Beats – Are They Dangerous?
PVC’s are common. Some people are troubled by just a few PVC’s where as others may have a PVC heart beat almost every other beat and not even notice it. Apart from being annoying to some (symptoms are sometimes described as heart flutter), are they of long-term significance? In this article we will look at…
Afib with RVR – When The Heart Races Out Of Control
What Is Afib with RVR? Afib with RVR refers to atrial fibrillation with rapid ventricular rate. Usually the heart is like clockwork, the top (collecting) chambers beat then the bottom (main pumping) chambers sense this and also beat, and so on, in a nice regular fashion just like a clock ticking second after second. Usually…
Atrial Fibrillation – Part 2 – Blood thinners
By Julian Booker MD Although we identify only four chambers with a normal human heart, the left atrium has a small finger-like pouch attachment most commonly called the appendage. Blood flow within the appendage can be slower than the rest of the left atrium. Although many cardiologists would argue, the left atrial appendage does have…
Atrial Fibrillation – Part 1 – What is it?
Atrial fibrillation, sometimes called a-fib, is the commonest cardiac arrhythmia (abnormal heart rhythm). In contrast to the metronome-like heart rhythm that we are used to, atrial fibrillation is characterized by an irregularly irregular heartbeat. If you were to check your pulse, there would be no pattern. The timing of your heartbeat would almost seem random.…
Stroke – Part 1 – Types of Stroke
By Julian Booker MD Stroke falls under the category of cerebrovascular disease meaning disease involving the blood vessels of the central nervous system (brain, spinal cord and visual system). We all know someone that has had a stroke but many of us do not know what a stroke is. I have heard people refer to…
Diastolic Heart Failure
Diastolic heart failure, is when you have heart failure with a near normal (preserved) ejection fraction. This type of heart failure is related more to the heart’s inability to relax. Diastolic Heart Failure sounds like a really scary thing, but don’t write your will yet. Learn the facts from a world renowned cardiologist.
