Vascular Dementia Can Happen to Anyone

…of the time high blood pressure is the cause. But it can also happen in people with arteriosclerosis, valvular disease, congestive heart failure, atrial fibrillation, and pacemaker therapy. The classic signs of VaD are slowed thinking, memory problems, confusion that often worsens at night, personality…

Common Side Effects of Beta Blockers

Low-dose beta blockers are effective in treatment for atrial fibrillation and lowering blood pressure levels. They also help prevent damage to the heart when oxygen flow is reduced. Research shows that taking beta blockers following a heart attack protects against arrhythmias that can develop as a result…

Stroke 101: Risk Factors for Stroke

…have higher rates of hypertension, diabetes, obesity, and tobacco use, all of which are independent risk factors for stroke) * High blood pressure * Atrial fibrillation * High inflammation marker scores, such as CRP, homocysteine, fibrinogen, and Lp(a) While the symptoms some strokes are easy to recognize—weakness…

Respiratory Sinus Arrhythmia and PACs

…relatively gradual slowing and speeding of the heart, like your foot on the gas pedal on normal traffic. Premature Atrial Contractions (PACs) As for PACs, this is an abbreviation for a premature atrial contraction generated by the SA node, or perhaps another electrical cell in the atria outside the usual conduction…

Is Your Cell Phone Causing Heart Problems?

…syncope, brief loss of consciousness (LOC) and had tachycardia (abrupt, rapid heartbeat). * Two people had a heart attack. * One person developed atrial fibrillation. That was 1970. Then, in 2010 Canadian Magda Havas confirmed that 20% of healthy subjects developed cardiac arrhythmias when provoked…

The Most Common Blood Thinners

…from a stroke if you have mechanical heart valves, atrial fibrillation or had an extensive heart attack (scar tissue weakens contraction of the left ventricle, which may allow blood to stagnate and clot). Blood thinners are also prescribed for atrial fibrillation, mechanical heart valves, and prevention…

What are Cardiac Arrhythmias?

…contracts prematurely. A premature atrial contraction is when the atrium (one of the two top chambers of the heart) contracts prematurely. We frequently see PVCs in women who have mitral valve prolapse. These irregularities are usually not a problem for healthy people. Atrial fibrillation is another cardiac…

The SA Node: An Intrinsic Heart Pacemaker

…Pacemaker We look first to the "sinus node," which is up atop the inside of the right atrium in the coronary "sinus," not unlike a nasal sinus. This sino-atrial node is also called the "SA node," and has the huge responsibility to stimulate each and every heart beat for a lifetime. Not even a lunch break for…

Even Mildly High Blood Pressure Ups Stroke Risk, Significantly

…start taking stroke prevention measures early. To me, this is even more important if you have other stroke risk factors like a family history and atrial fibrillation, even if the statistics based on this one meta-analysis reports pre-hypertension as an independent risk factor at this time. It only makes…

Should You Take Blood-Thinning Drugs?

…blood and prevent blood clots which can cause strokes. This is especially true if you have mechanical heart valves, suffered an embolic stroke, have atrial fibrillation (AF) or had an extensive heart attack. But, like any drug, Coumadin does have side effects. The major one is excessive bleeding (bleeding…
