Mandrola lists as Steps 5-8 (Steps 1-4 are reassurance) for PVC treatment his “four legs of the table of health”: You can’t always control external stresses, but several factors in your lifestyle are key to managing how those stresses activate your sympathetic nervous system and trigger troubling PVCs.ĭr. This is also a typical story my patient’s relate: troubling palpitations seem to melt away when they retire or change to less stressful occupations, or as they recover from depression/anxiety/grief related to death of loved ones, divorce or illness. I rarely get PVCs these days, as the major source of stress in my personal life has gone away. Stress activates our sympathetic nervous system, causing the release of hormones from the adrenal gland that prepare us for “fight or flight.” These hormones stimulate the heart to beat faster and harder and often trigger PVCs. I know exactly what causes them: stress and anxiety. I feel them as a sense that something has shifted inside my chest briefly, like my breath has been interrupted, like my heart has hiccoughed. If I didn’t know about PVCs and hadn’t made the diagnosis very quickly by hooking myself up to an ECG monitor in my office, I know I would have become very anxious about it. It’s probably time I revealed that I have PVCs. Arkansas does not currently have a supply of potassium chloride, the killing drug specified in its execution protocol, but believes it can obtain supplies of that drug prior to the scheduled execution dates”) According to : “The hurried schedule appears to be an attempt to use the state’s current supply of eight doses of midazolam, which will expire at the end of April. (In fact, Arkansas is hurrying to execute 8 men between April 17 and 27 utilizing KCl. Potassium infusions are used as part of a “lethal injection” in executions because extreme hyperkalemia causes the heart to stop beating. If you have kidney disease you are much more likely to develop hyperkalemia, or high K, and you want to avoid these high K foods.
Yogurt (and I recommend full fat yogurt, of course) is a great source as well. Avocados are a great source of K and contain lots of healthy fat. The charts show that a medium tomato contains as much K as a medium banana with a third of the calories. Most patients I talk to about low K immediately assume they should eat more bananas, but lots of fresh fruit and vegetables contain as much or more K than bananas. An alternative to potassium supplements is ramping up how much potassium you consume in your diet. I usually give them a prescription for potassium chloride (KCl) 10-20 meq daily to accomplish raising the level to >4. Most of my symptomatic PVC patients with potassium less than 4 find significant improvement with potassium supplementation. The normal range of potassium (K) is considered to be 3.5 to 5 meq/L, however, I have found that PVCs are more frequent when the potassium is less than 4.
The body regulates potassium levels closely, due to its importance in the electrical activities involved in cardiac, muscular and neurological function. There are lots of other infrequent causes including excess licorice consumption. Hypokalemia can also develop if you are vomiting, having diarrhea, or sweating excessively. Patients who take diuretics like hydrochlorothiazide (HCTZ, often used for high blood pressure) or furosemide (Lasix, often used for leg swelling or heart failure), are at high risk for hypokalemia with potassium levels less than 3.5 meQ/L. Low potassium levels (hypookalemia) have been clearly associated with an increase in ventricular ectopy.
