Mayo Clinic researchers recently published a study that shows the proper use of masks reduces the spread of respiratory droplets. The findings strongly support the protective value and effectiveness of widespread mask use and maintaining physical distance in reducing the spread of COVID-19. Reporter Jason Howland has more in this Mayo Clinic Minute.
ACL tears can sideline an athlete or crush an Olympic dream. It’s a common knee injury affecting nearly twice as many women than men. Dr. Cedric Ortiguera, a Mayo Clinic orthopedic surgeon and sports medicine specialist, says 150,000‒200,000 ACL injuries occur each year in the U.S., and that number is growing as more children become involved in competitive sports year-round. The good news is that surgery can help get some athletes get back in the game.
Tachycardia is the medical term for a heart rate over 100 beats per minute. There are many heart rhythm disorders (arrhythmias) that can cause tachycardia.
Types of tachycardia
There are many different types of tachycardia. They’re grouped according to the part of the heart responsible for the fast heart rate and cause of the abnormally fast heartbeat. Common types of tachycardia include:
- Atrial fibrillation. Atrial fibrillation is a rapid heart rate caused by chaotic, irregular electrical impulses in the upper chambers of the heart (atria). These signals result in rapid, uncoordinated, weak contractions of the atria.Atrial fibrillation may be temporary, but some episodes won’t end unless treated. Atrial fibrillation is the most common type of tachycardia.
- Atrial flutter. In atrial flutter, the heart’s atria beat very fast but at a regular rate. The fast rate results in weak contractions of the atria. Atrial flutter is caused by irregular circuitry within the atria.Episodes of atrial flutter may go away themselves or may require treatment. People who have atrial flutter also often have atrial fibrillation at other times.
- Supraventricular tachycardia (SVT). Supraventricular tachycardia is an abnormally fast heartbeat that starts somewhere above the lower chambers of the heart (ventricles). It’s caused by abnormal circuitry in the heart that is usually present at birth and creates a loop of overlapping signals.
- Ventricular tachycardia. Ventricular tachycardia is a rapid heart rate that starts with abnormal electrical signals in the lower chambers of the heart (ventricles). The rapid heart rate doesn’t allow the ventricles to fill and contract efficiently to pump enough blood to the body.Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. But episodes lasting more than a few seconds can become a life-threatening medical emergency.
- Ventricular fibrillation. Ventricular fibrillation occurs when rapid, chaotic electrical impulses cause the lower heart chambers (ventricles) to quiver instead of pumping necessary blood to the body. This can be deadly if the heart isn’t restored to a normal rhythm within minutes with an electric shock to the heart (defibrillation).Ventricular fibrillation may occur during or after a heart attack. Most people who have ventricular fibrillation have an underlying heart disease or have experienced serious trauma, such as being struck by lightning.
When it comes to fighting cancer or living with a cancer diagnosis, does what you eat make a difference? On Mayo Clinic Q&A, Dr. John Shin, a hematologist/oncologist, discusses nutrition and cancer.
The department of Otolaryngology offers telemedicine as a safe, secure and convenient way to consult with our care teams. Advanced planning, follow up visits and attending a consultation from a distant with a family member are beneficial ways to utilize telemedicine. See here for information on our clinic and specialty groups related to the department of Otolaryngology. https://www.mayoclinic.org/department…
Otorhinolaryngology is a surgical subspecialty within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians.
Multiple myeloma is a relatively uncommon form of blood cancer that affects less than 1% of the U.S. population, according the American Cancer Society. People younger than 45 rarely get the disease, and it occurs more in older men than women. And your risk is doubled if you’re African American.
