Premature ventricular contractions are common. Many people have premature ventricular contractions without any symptoms. Premature ventricular contractions may be more common among older patients, patients with high blood pressure, and patients with heart disease.

Full Answer. The midnight sun is a natural phenomenon. It reaches its peak during the summer solstice, which occurs around June 21 each year. On the day of the solstice, areas in Norway and in other regions around the world north of the Arctic Circle may receive almost 24 hours of sunlight. The sun in these areas continues to shine through the midnight hour, which is how the term midnight sun arose.

In Fairbanks, during the darkest day of the year, the sun rises for about three hours just as in the summer it only sets for three hours. The midnight sun is only found above the arctic circle, when the sun dips but never fully sets. The arctic circle is 66 degrees, 33 minutes and 44 seconds latitude.
