QT Preventative Measures
Dr. Michael Ackerman reviews the five overarching QT preventative safety measures that patients with long QT syndrome (LQTS) should observe.

Sudden Arrhythmia Death Syndromes and Vaccinations
Dr. Michael Ackerman, a genetic cardiologist from Mayo Clinic, discusses concerns about vaccinations and flu shots for patients with genetic heart rhythm conditions like Brugada Syndrome (BrS), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), and Long QT Syndrome (LQTS). The benefits of being vaccinated far exceed the low risk the vaccination or potential fever could have on a genetic heart rhythm condition.
Cardiac Channelopathies: Who Needs an ICD?
In this 35 minute lecture, Mayo Clinic Genetic Cardiologist Michael J. Ackerman, M.D., Ph.D., discusses who should and, more importantly, who should not receive an implantable cardioverter-defibrillator (ICD) for the management of their cardiac channelopathies, such as Brugada Syndrome (BrS), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), and Long QT Syndrome.

Sudden Cardiac Death Risk Stratification in Athletes
Identifying athletes at risk for SCD can be like looking for a needle in a haystack. In a video originally posted on TheHeart.org | Medscape Cardiology, Stephen Hammill, MD, talks to Michael J Ackerman, MD, and Douglas Packer, MD, about the many challenges involved, including why we need to think carefully about ECG screening and the importance of a proper history and physical for all patients, not just athletes.
A Genetic Test Prediction Score for Hypertrophic Cardiomyopathy
Dr. Michael J. Ackerman, a genetic cardiologist and Director of Mayo Clinic's Windland Smith Rice Sudden Death Genomics Laboratory in Rochester, MN, explains in his article appearing in the June 2014 issue of Mayo Clinic Proceedings, the development of a simple 5-point scoring method which clinicians and genetic counselors can use in their pre-genetic counseling sessions with patients diagnosed with hypertrophic cardiomyopathy.

Treating malignant VF syndromes by Left Cardiac Sympathetic Denervation (LCSD)
In this interview, Professor Michael J. Ackerman from the Mayo Clinic at Rochester MN, speaks about the Left Cardiac Sympathetic Denervation Therapy (LCSD) in patients with malignant VF syndromes. Though this technique itself is not very new but known for decades it is going to be a valuable further treatment option among pharmacologic therapies and ICD. The pediatric cardiologist successfully treated infants, small children, and adults and gives an overview of how the procedure is performed, what complications could occur, which patients would profit from an LCSD, and which ones would not. And he points out: LCSD is helpful, but it is not a cure. Ackerman presented this promising treatment option at the 5th Euro VT/VF 2013 meeting in Berlin, Germany.
Eligibility recommendations for competitive athletes with cardiovascular abnormalities
Professor Michael J. Ackerman, M.D., Ph.D. from the Mayo Clinic at Rochester MN spoke at the 5th Euro VT/VF Meeting about athletes with arrhythmias like the Long QT Syndrome or the Brugada Syndrome taking part in competitive sports. The existing guidelines in the US and Europe are not evidence-based but just well-meant advice trying to prevent any risk for these athletes, Ackerman says. He called for a paradigm shift to provide the athletes with valuable data and information to decide for themselves whether they are willing to take the residual risk and continue their training and competitive activity.
Guidelines for Sports Participation in Athletes with Heart Disease
Alfred A. Bove, MD, PhD, interviews Michale John Ackerman, MD, PhD, about guidelines for sports participation in athletes with heart disease.
When in Doubt, Kick them Out? Long QT Syndrome (LQTS) Sports Guidelines
In a video originally posted on www.theheart.org, Mayo Clinic cardiologist Douglas Packer, M.D., and Michael Ackerman, M.D., Ph.D., cardiologist and Director of Mayo Clinic's Long QT Syndrome Clinic, discuss Long QT Syndrome, the consequences of guideline-based recommendations for disqualification, and the JAMA article discussing sports guidelines for Long QT syndrome patients.

After Death Genetic Testing - Mayo Clinic
Mayo Clinic scientists presented research at the American Heart Associations Scientific Sessions 2009 in Orlando, showing that postmortem testing to identify genetic mutations for sudden unexplained death could be a less expensive manner to determine first-degree relatives' risk. Dr. Michael Ackerman, the study's senior author, talks about the research.
