She exercised regularly and ate a healthy diet. Now at the age of 34 she was having severe palpitations. How could this be? Metoprolol succinate er side affects you think about it, the heart is an amazing organ.
It beatstimes a day. Most of the time, every heart beat is perfectly timed. Sometimes, the heart fires prematurely. If you are taking your pulse at the time this happens the premature beat is not detected and it feels as if you have skipped a beat.
You can see this clearly on the EKG with this article. Every third beat is a PVC which is characterized by a big wide electrical signal from the lower chambers of the heart. For others, they feel each and every misfire and it causes them severe symptoms. You can have a premature beat arise from either the upper or lower chambers of the heart.
If the premature beat is arising from the upper chambers of the heart it is called a premature atrial contraction PAC and if it is from the lower chambers of the heart it is called a premature ventricular contraction PVC. To figure out what was going on, we put her on a Holter heart monitor for 48 hours and scheduled her for a stress echo. A stress echo is a treadmill stress test with a cardiac ultrasound.
The ultrasound of the heart, also known as an echocardiogram, is done before exercise and then repeated at peak exercise. The purpose of the stress echo is to make sure there is nothing structurally wrong with the heart that is causing the PVCs.
I personally like the stress echo because no IV is needed and there is no radiation with this test. It can also be helpful to see what happens to the PVCs with exercise. Fortunately, her stress echo was totally normal. Lisa was still worried as she had 3 small children. As you might imagine, Lisa wanted to know what was causing her PVCs. Structural heart disease, side affects of sertraline a blockage in an artery of the heart or even heart failure, can certainly cause PVCs.
Most of the patients who come to see me for PVCs, like Lisa, want to know what is causing their condition. Fortunately, Lisa did not have any structural heart disease. For people without structural heart disease, like Lisa, with her normal stress echo and MRI studies, we often do not know the exact cause of PVCs.
For whatever reason, one particular cell or a cluster of heart cells, will spontaneously kick off these electrical signals. These PVCs often wax and wane in intensity over the years. In many cases, lifestyle modification can cause the PVCs to go away or improve.
As mentioned at the beginning of this article, every living and breathing human being has PVCs. There are certain genetic abnormalities that can cause PVCs but yet are sometimes not picked up on a stress echo or a cardiac MRI. For many patients, just metoprolol succinate er side affects their PVCs are benign takes care of the problem and relieves the stress.
I have found over the years that my patients who are most bothered by PVCs are often my most anxious patients. When you are stressed the body releases adrenalin and cortisol, among other stress hormones. These stress hormones put a strain on the heart and can trigger PVCs. I have seen many cases of severe PVCs that have all resolved once the patient gets their stress and anxiety under control. There is some fascinating research being done by my good metoprolol succinate er side affects, Dr.
Shivkumar, at UCLA on cardiac nerves, metoprolol succinate er side affects. Regardless of the cause, if you suffer from stress or anxiety the first step is to get this under control. Do something each day to relieve stress. For example, yoga has been shown to be very helpful in controlling arrhythmias.
Daily meditation is also highly effective. Do you consume a lot of caffeine? Do you take stimulant cold medicines, ADHD medications, or stimulant inhalers for asthma? Do you use any nicotine products, alcohol, or recreational drugs? To learn more about the effect of caffeine to PVCs, please read this article I recently published.
Amazingly, many of my PVC patients just do not get enough sleep at night. With sleep deprivation, your stress hormones go way up which can trigger PVCs. Have a set sleep schedule and get at least 7 hours of rejuvenating sleep. If you are overweight, or have a neck size of roth plan administration or more in a man 16 or more in a womanyou may have sleep apnea.
This is a condition where people snore loudly at night and metoprolol succinate er side affects stop breathing. This causes oxygen levels in the body to plummet and can be another cause of sleep deprivation and PVCs.
If your spouse or sleeping partner tells you that you snore, or that you sometimes stop breathing in your sleep, talk to your doctor now about getting tested for sleep apnea. Fortunately, most cases of sleep apnea are reversible with weight loss. If you are struggling with getting at least seven metoprolol succinate er side affects of rejuvenating sleep, please read my article Blog 16 Ten Ways to Cure Insomnia without Medications.
You may have additional triggers besides stress, stimulants, or sleep deprivation. Vagal Indomethacin indocin after surgery are triggered by activation of the vagus nerve, like after a big meal or eating certain foods. Just making sure you are getting enough potassium and magnesium in your diet may be all that is necessary to get PVCs under control. These electrolytes have a calming effect on the cells of the heart.
Fortunately, the foods highest in potassium and magnesium are the healthiest foods. However, people suffering from kidney disease should be careful with high potassium and magnesium foods, metoprolol succinate er side affects. In addition to bananas, other excellent sources of potassium include spinach, beans, broccoli, and cantaloupe.

As with most arrhythmias, not getting enough exercise or extreme exercise marathon or ultra marathon running, long distance competitive cycling, triathlons, etc.
I recommend at least 30 minutes of moderate intensity exercise or 15 minutes of high intensity exercise AND 10, steps, as confirmed by a pedometer, each day for my patients. For those people who enjoy extreme levels of exercise marathoners or ultra marathoners, long distance competitive cyclists, triathletes, etc. If you have not been exercising regularly, talk with your doctor first before starting an exercise program. For some of my patients they find that when their blood pressure spikes high they are more likely to experience PVCs.
If your blood pressure often reads higher than this, metoprolol succinate er side affects, please work with your physician on getting your blood pressure under control.
Often PVCs can be triggered by other medical conditions. Work with your physicians in getting quit smoking alaska conditions under control. Sometimes other medications can trigger PVCs. For example, metoprolol succinate er side affects, diuretics or water pills cause you to lose electrolytes. Electrolyte depletion can trigger PVCs. These include many antibiotics, antidepressants, and other medications.
For a list of many of the medications that lengthen the QT interval, please metoprolol succinate er side affects this list of medications. In rare cases, my patients are so bothered fluoxetine and alcohol PVCs that we need to try a medication when numbers above do not work or when patients are unable to make the necessary lifestyle changes.
Often, the side effects from one of these medications is worse than the PVC symptoms. If we must try a medication, metoprolol succinate er side affects, I generally start with a beta-blocker. I find that in about half of the patients I see, beta-blockers help with PVCs. Anti-arrhythmics always make me nervous as they can increase your risk of a cardiac arrest or premature death. In an ablation, we go in to the heart with a catheter, map out the source of the PVCs, and then cauterize or freeze the areas of the heart kicking off the PVCs.
I find that the most challenging part of the procedure is getting the patient to have enough PVCs during the procedure. It is important to remember that everyone will get a PVC from time to time.
When the heart beatstimes each day it is bound to occasionally misfire. This is a normal thing. Please feel free to leave a comment or post a question below, metoprolol succinate er side affects.
