Meet Dr. Joshua Quinones, Top Pediatric Cardiologist in Houston, TX

Dr. Joshua Quiňones

Pediatric cardiologists safeguard patients’ cardiovascular health, including children and young people. Their importance extends beyond diagnosis and treating heart-related conditions to encompass preventive care, early intervention, and general wellness.

General cardiologists specialize in identifying and treating a spectrum of adult cardiovascular diseases. They contribute to preventing heart disease by assessing risk factors, promoting heart-healthy lifestyles, and implementing early interventions. Regular checkups with a cardiologist help adults monitor their heart health, control conditions such as hypertension or cholesterol disorders, and receive timely treatment for emerging heart problems.

Pediatric cardiologists, on the other hand, focus on the unique cardiovascular needs of infants, children, and adolescents. The importance of pediatric cardiology lies in addressing congenital heart defects and acquired heart conditions specific to this demographic. These specialists are experts at interpreting subtle signs of cardiac problems in young patients, providing early diagnosis, and devising personalized treatment plans that consider the changing needs of growing hearts.

The importance of cardiologists for children and young patients lies in the potential to mitigate long-term complications and improve quality of life. For example, quickly identifying and treating congenital heart defects can improve outcomes and minimize the impact on a child’s overall health and development. Pediatric cardiologists work near other healthcare professionals to provide comprehensive care and meet young patients’ cardiac and general health needs.

In addition, these specialists contribute to the psychological and emotional well-being of the patients and families. Dealing with heart disease, especially in children, can be emotionally challenging.

A child or adolescent should see a cardiologist when they have signs or symptoms that suggest a possible problem with their heart health. While routine pediatric checkups often include essential cardiac evaluations, specific indications may trigger a referral to a pediatric cardiologist. Some common reasons for a child or adolescent to see a cardiologist include the following:

Congenital heart defects: If a child is born with a congenital heart defect, a pediatric cardiologist will be implicated in the care and treatment of the condition.

Heart murmurs: The presence of a heart murmur may warrant further evaluation by a cardiologist to determine its cause and significance.

Chest pain: Persistent or recurrent chest pain, especially during physical activity, may require cardiology evaluation to rule out cardiac problems.

Irregular heartbeat (arrhythmia): If there are concerns about irregular heartbeats or palpitations, a cardiologist may perform specialized tests to evaluate the heart’s electrical activity.

Syncope (fainting): Recurrent fainting episodes may indicate underlying heart problems that require investigation by a cardiologist.

Family history of heart disease: A cardiologist can monitor the child for possible inherited risks if there is a family history of congenital heart disease or other heart conditions.

Hypertension: Elevated blood pressure in children can be an early sign of possible heart-related problems and may prompt a visit to a cardiologist.

Failure to thrive or develop: In some cases, poor growth or developmental delay may be related to cardiac problems, requiring evaluation by a pediatric cardiologist.

Exercise-related symptoms: Symptoms such as shortness of breath, fatigue, or chest discomfort during exercise may require cardiac evaluation.

Systemic diseases: Certain systemic diseases, such as Kawasaki disease or rheumatic fever, can affect the heart and may require the expertise of a cardiologist.

It is important to remember that these are general guidelines, and each case is unique. Pediatricians are usually the first line of defense, performing initial evaluations and referring to a pediatric cardiologist when necessary. Regular well-child checkups, with cardiac evaluations, also help in the early identification of potential problems.

Suppose parents or caregivers notice any concerning symptoms in a child or adolescent. In that case, it is critical to pursue immediate medical attention and consult with a professional who can determine if a referral to a pediatric cardiologist is necessary. Early detection and intervention can significantly impact pediatric heart health outcomes.




Dr. Joshua A. Quinones, following the same practice guideline, prefers the prevention of diseases; therefore, if your child has a family background of heart conditions or experiences symptoms, it is advisable to schedule an appointment with him or one of the team cardiologists.

Please do it right by scheduling an appointment at the first symptoms and obtaining an early diagnosis of cardiovascular disease.
